article | DOI |
Abstract: The program AceDRG is designed for the derivation of stereochemical information about small molecules. It uses local chemical and topological environment-based atom typing to derive and organize bond lengths and angles from a small-molecule database: the Crystallography Open Database (COD). Information about the hybridization states of atoms, whether they belong to small rings (up to seven-membered rings), ring aromaticity and nearest- neighbour information is encoded in the atom types. All atoms from COD have been classified according to the generated atom types. All bonds and angles have also been classified according to the atom types and, in a certain sense, bond types. Derived data are tabulated in a machine-readable form that is freely available from CCP4. AceDRG can also generate stereochemical information, provided that the basic bonding pattern of a ligand is known. The basic bonding pattern is perceived from one of the computational chemistry file formats, including SMILES, mmCIF, SDF MOL and SYBYL MOL2 files. Using the bonding chemistry, atom types, and bond and angle tables generated from COD, AceDRG derives the ‘ideal’ bond lengths, angles, plane groups, aromatic rings and chirality information, and writes them to an mmCIF file that can be used by the refinement program REFMAC5 and the model-building program Coot. Other refinement and model-building programs such as PHENIX and BUSTER can also use these files. AceDRG also generates one or more coordinate sets corresponding to the most favourable conformation(s) of a given ligand. AceDRG employs RDKit for chemistry perception and for initial conformation generation, as well as for the interpretation of SMILES strings, SDF MOL and SYBYL MOL2 files. |

article | DOI |
Abstract: A freely available small-molecule structure database, the Crystallography Open Database (COD), is used for the extraction of molecular-geometry information on small-molecule compounds. The results are used for the generation of new ligand descriptions, which are subsequently used by macromolecular model- building and structure-refinement software. To increase the reliability of the derived data, and therefore the new ligand descriptions, the entries from this database were subjected to very strict validation. The selection criteria made sure that the crystal structures used to derive atom types, bond and angle classes are of sufficiently high quality. Any suspicious entries at a crystal or molecular level were removed from further consideration. The selection criteria included (i) the resolution of the data used for refinement (entries solved at 0.84 A resolution or higher) and (ii) the structure-solution method (structures must be from a single-crystal experiment and all atoms of generated molecules must have full occupancies), as well as basic sanity checks such as (iii) consistency between the valences and the number of connections between atoms, (iv) acceptable bond-length deviations from the expected values and (v) detection of atomic collisions. The derived atom types and bond classes were then validated using high-order moment-based statistical techniques. The results of the statistical analyses were fed back to fine-tune the atom typing. The developed procedure was repeated four times, resulting in fine-grained atom typing, bond and angle classes. The procedure will be repeated in the future as and when new entries are deposited in the COD. The whole procedure can also be applied to any source of small-molecule structures, including the Cambridge Structural Database and the ZINC database. |

Abstract: There are many methods that can be used to incorporate concepts of crystallography into the learning experiences of students, whether they are in elementary school, at university or part of the public at large. It is not always critical that those who teach crystallography have immediate access to diffraction equipment to be able to introduce the concepts of symmetry, packing or molecular structure in an age- and audience-appropriate manner. Crystallography can be used as a tool for teaching general chemistry concepts as well as general research techniques without ever having a student determine a crystal structure. Thus, methods for younger students to perform crystal growth experiments of simple inorganic salts, organic compounds and even metals are presented. For settings where crystallographic instrumentation is accessible (proximally or remotely), students can be involved in all steps of the process, from crystal growth, to data collection, through structure solution and refinement, to final publication. Several approaches based on the presentations in the MS92 Microsymposium at the IUCr 23rd Congress and General Assembly are reported. The topics cover methods for introducing crystallography to undergraduate students as part of a core chemistry curriculum; a successful short-course workshop intended to bootstrap researchers who rely on crystallography for their work; and efforts to bring crystallography to secondary school children and non-science majors. In addition to these workshops, demonstrations and long-format courses, open-format crystallographic databases and three-dimensional printed models as tools that can be used to excite target audiences and inspire them to pursue a deeper understanding of crystallography are described. |

article | DOI URL |
Abstract: A syntax-correcting CIF parser, COD::CIF::Parser, is presented that can parse CIF 1.1 files and accurately report the position and the nature of the discovered syntactic problems. In addition, the parser is able to automatically fix the most common and the most obvious syntactic deficiencies of the input files. Bindings for Perl, C and Python programming environments are available. Based on COD::CIF::Parser, the cod-tools package for manipulating the CIFs in the Crystallography Open Database (COD) has been developed. The cod-tools package has been successfully used for continuous updates of the data in the automated COD data deposition pipeline, and to check the validity of COD data against the IUCr data validation guidelines. The performance, capabilities and applications of different parsers are compared. |

Vol. 40(D1), pp. D420-D427 |
article | DOI URL |
Abstract: Using an open-access distribution model, the Crystallography Open Database (COD, http://www.crystallography.net) collects all known ‘small molecule / small to medium sized unit cell’ crystal structures and makes them available freely on the Internet. As of today, the COD has aggregated ∼150 000 structures, offering basic search capabilities and the possibility to download the whole database, or parts thereof using a variety of standard open communication protocols. A newly developed website provides capabilities for all registered users to deposit published and so far unpublished structures as personal communications or pre-publication depositions. Such a setup enables extension of the COD database by many users simultaneously. This increases the possibilities for growth of the COD database, and is the first step towards establishing a world wide Internet-based collaborative platform dedicated to the collection and curation of structural knowledge. |

Abstract: Crystallographic investigations deliver high-accuracy information about positions of atoms in crystal unit cells. For chemists, however, the structure of a molecule is most often of interest. The structure must thus be reconstructed from crystallographic files using symmetry information and chemical properties of atoms. Most existing algorithms faithfully reconstruct separate molecules but not the overall stoichiometry of the complex present in a crystal. Here, an algorithm that can reconstruct stoichiometrically correct multimolecular ensembles is described. This algorithm uses only the crystal symmetry information for determining molecule numbers and their stoichiometric ratios. The algorithm can be used by chemists and crystallographers as a standalone implementation for investigating above-molecular ensembles or as a function implemented in graphical crystal analysis software. The greatest envisaged benefit of the algorithm, however, is for the users of large crystallographic and chemical databases, since it will permit database maintainers to generate stoichiometrically correct chemical representations of crystal structures automatically and to match them against chemical databases, enabling multidisciplinary searches across multiple databases. |

Their binding to recombinant human carbonic anhydrase (hCA) isozymes I, II, VII, and XIII was determined by isothermal titration calorimetry and thermal shift assay. The designed S-alkylated benzimidazole derivatives exhibited stronger binding than the indapamide-like N-alkylated benzimidazoles, with the K(d) reaching about 50-100 nM with drug-targeted hCAs VII and XIII. The cocrystal structures of selected compounds with hCA II were determined by X-ray crystallography, and structural features of the binding event were revealed. |

Abstract: EcoRII restriction endonuclease is specific for the 5'-CCWGG sequence (W stands for A or T); however, it shows no activity on a single recognition site. To activate cleavage it requires binding of an additional target site as an allosteric effector. EcoRII dimer consists of three structural units: a central catalytic core, made from two copies of the C-terminal domain (EcoRII-C), and two N-terminal effector DNA binding domains (EcoRII-N). Here, we report DNA-bound EcoRII-N and EcoRII-C structures, which show that EcoRII combines two radically different structural mechanisms to interact with the effector and substrate DNA. The catalytic EcoRII-C dimer flips out the central T:A base pair and makes symmetric interactions with the CC:GG half-sites. The EcoRII-N effector domain monomer binds to the target site asymmetrically in a single defined orientation which is determined by specific hydrogen bonding and van der Waals interactions with the central T:A pair in the major groove. The EcoRII-N mode of the target site recognition is shared by the large class of higher plant transcription factors of the B3 superfamily. |

Abstract: The X-ray crystal structure of Citrobacter freundii restriction endonuclease Cfr10I has been determined at a resolution of 2.15 A by multiple isomorphous replacement methods and refined to an R-factor of 19.64%. The structure of Cfr10I represents the first structure of a restriction endonuclease recognizing a degenerated nucleotide sequence. Structural comparison of Cfr10I with previously solved structures of other restriction enzymes suggests that recognition of specific sequence occurs through contacts in the major and the minor grooves of DNA. The arrangement of the putative active site residues shows some striking differences from previously described restriction endonucleases and supports a two-metal-ion mechanism of catalysis. |

Abstract: The MunI restriction enzyme recognizes the palindromic hexanucleotide sequence C/AATTG (the '/' indicates the cleavage site). The crystal structure of its active site mutant D83A bound to cognate DNA has been determined at 1.7 A resolution. Base-specific contacts between MunI and DNA occur exclusively in the major groove. While DNA-binding sites of most other restriction enzymes are comprised of discontinuous sequence segments, MunI combines all residues involved in the base-specific contacts within one short stretch (residues R115-R121) located at the N-terminal region of the 3(10)4 helix. The outer CG base pair of the recognition sequence is recognized solely by R115 through hydrogen bonds made by backbone and side chain atoms to both bases. The mechanism of recognition of the central AATT nucleotides by MunI is similar to that of EcoRI, which recognizes the G/AATTC sequence. The local conformation of AATT deviates from the typical B-DNA form and is remarkably similar to EcoRI-DNA. It appears to be essential for specific hydrogen bonding and recognition by MunI and EcoRI. |

Abstract: The crystal structure of the NgoMIV restriction endonuclease in complex with cleaved DNA has been determined at 1.6 A resolution. The crystallographic asymmetric unit contains a protein tetramer and two DNA molecules cleaved at their recognition sites. This is the first structure of a tetrameric restriction enzyme-DNA complex. In the tetramer, two primary dimers are arranged back to back with two oligonucleotides bound in clefts on opposite sides of the tetramer. The DNA molecules retain a B-type conformation and have an enclosed angle between their helical axes of 60 degrees. Sequence-specific interactions occur in both the major and minor grooves. Two Mg2+ ions are located close to the cleaved phosphate at the active site of NgoMIV. Biochemical experiments show that interactions between the recognition sites within the tetramer greatly increase DNA cleavage efficiency. |

Abstract: Crystal structures of Type II restriction endonucleases demonstrate a conserved common core and active site residues but diverse structural elements involved in DNA sequence discrimination. Comparative structural analysis of restriction enzymes recognizing the same nucleotide sequence might therefore contribute to our understanding of the structural diversity of specificity determinants within restriction enzymes. We have solved the crystal structure of the Bacillus stearothermophilus restriction endonuclease Bse634I by the multiple isomorphous replacement technique to 2.17 A resolution. Bse634I is an isoschisomer of the Cfr10I restriction enzyme whose crystal structure has been reported previously. Comparative structural analysis of the first pair of isoschisomeric enzymes revealed conserved structural determinants of sequence recognition and catalysis. However, conformations of the N-terminal subdomains differed between Bse634I/Cfr10I, suggesting a rigid body movement that might couple DNA recognition and catalysis. Structural similarities extend to the quaternary structure level: crystal contacts suggest that Bse634I similarly to Cfr10I is arranged as a tetramer. Kinetic analysis reveals that Bse634I is able to interact simultaneously with two recognition sites supporting the tetrameric architecture of the protein. Thus, restriction enzymes Bse634I, Cfr10I and NgoMIV, recognizing overlapping nucleotide sequences, exhibit a conserved tetrameric architecture that is of functional importance. |

Abstract: Gel shift analysis reveals [Lagunavicius, A., & Siksnys, V. (1997) Biochemistry 36 (preceding paper in this issue)] that at pH 8.3 in the absence of Mg2+, MunI restriction endonuclease exhibits little DNA binding specificity, as compared with the D83A and E98A mutants of MunI. This suggests that charged carboxylate residue(s) influence the DNA binding specificity of MunI. In our efforts to establish the determinants of MunI binding specificity, we investigated the possible role of the ionic milieu, and we found that lowering pH or elevating Ca2+ levels per se induces specific DNA recognition by WT MunI. In contrast to the binding experiments at pH 8.3, gel shift analysis at pH 6.5 indicated tight sequence-specific binding of WT MunI in the absence of Mg2+, suggesting that protonation of active site carboxylate residue(s) which manifest anomalously high pKa value(s) control binding specificity. Interestingly, Ca2+ ion concentrations, which did not support DNA cleavage by MunI also induced DNA binding specificity in WT MunI at pH 8.3. To explore possible structural changes upon DNA binding, we then used a limited proteolysis technique. Trypsin cleavage of MunI-DNA complexes indicated that in the presence of cognate DNA the MunI restriction endonuclease became resistant to proteolytic cleavage, suggesting that binding of specific DNA induced a structural change. CD measurements confirmed this observation, suggesting minor secondary structural differences between complexes of MunI with cognate and noncognate DNA. These results therefore suggest that binding of MunI to its recognition sequence triggers a conformational transition that correctly juxtaposes active site carboxylate residues, which then chelate Mg2+ ions. In the absence of Mg2+ ions, at pH 8.3, conditions in which carboxylate groups would be expected to be completely ionized, electrostatic repulsion between charged carboxylates and phosphate oxygens is enhanced such as to interfere with specific DNA binding. Elimination of such repulsive constraints by replacement of carboxylate residues, by lowering pH, or by metal ion binding, then promotes MunI binding specificity. |

Abstract: It is thought that most of the type II restriction endonucleases interact with DNA as homodimers. Cfr10I is a typical type II restriction enzyme that recognises the 5'-Pu decreases CCGGPy sequence and cleaves it as indicated by the arrow. Gel-filtration and analytical ultracentrifugation data presented here indicate that Cfr10I is a homotetramer in isolation. The only SfiI restriction enzyme that recognises the long interrupted recognition sequence 5'-GGCCNNNNNGGCC has been previously reported to operate as a tetramer however, its structure is unknown. Analysis of Cfr10I crystals revealed that a single molecule in the asymmetric unit is repeated by D2 symmetry to form a tetramer. To determine whether the packing of the Cfr10I in the crystal reflects the quaternary structure of the protein in solution, the tryptophan W220 residue located at the putative dimer-dimer interface was mutated to alanine, and the structural and functional consequences of the substitution were analysed. Equilibrium sedimentation experiments revealed that, in contrast to the wild-type Cfr10I, the W220A mutant exists in solution predominantly as a dimer. In addition, the tetramer seems to be a catalytically important form of Cfr10I, since the DNA cleavage activity of the W220A mutant is < 0.1% of that of the wild-type enzyme. Further, analysis of plasmid DNA cleavage suggests that the Cfr10I tetramer is able to interact with two copies of the recognition sequence, located on the same DNA molecule. Indeed, electron microscopy studies demonstrated that two distant recognition sites are brought together through the DNA looping induced by the simultaneous binding of the Cfr10I tetramer to both sites. These data are consistent with the tetramer being a functionally important form of Cfr10I. |

Abstract: According to the crystal structure of Cfr10I restriction endonuclease the acidic residues D134, E71 and E204 are clustered together and presumably chelate metal ion(s) at the active site. Indeed, investigation of the DNA cleavage properties of substitutional mutants of Cfr10I D134A, E71Q, E71A and E204Q reveals that D134, E71 and E204 residues are essential for cleavage activity, supporting their active site function. Structural comparison indicates that the D134 residue of Cfr10I spatially overlaps with aspartate residues D91 and D74, from the invariant active site motifs 90PDX19EAK and 73PDX15DIK of EcoRI and EcoRV, respectively. However, structural studies in conjunction with mutational analyses suggest that the sequence motif 133PDX55KX13E corresponds to the active site of Cfr10I, but differs from canonical active site motifs of EcoRI and EcoRV. According to the crystal structure of Cfr10I the serine S188 residue from the 188SVK sequence motif is a spatial equivalent of the acidic residue from the (E/D)XK-part of the active site motif, which is conserved between EcoRI and EcoRV. Site-directed mutagenesis experiments of Cfr10I, however, revealed that the S188 was not so important for catalysis while the E204 residue located 2.8 A away indeed was essential for cleavage, suggesting that the glutamate E204 rather than the S188 residue contributes to the metal binding site in Cfr10I. In addition, model-building studies suggest that mutual interchange of the E204 and S188 residues should lead only to minor positional differences of the carboxylate residues of glutamate side-chains. The double mutant S188E/E204S was therefore prepared by site-directed mutagenesis where the active site motif 133PDX55KX13E of Cfr10I was changed to a canonical motif 133PDX53EVK, which is similar to that of EcoRI and EcoRV. Interestingly, the double mutant S188E/E204S of Cfr10I with redesigned active site structure, exhibited 10% of Wt cleavage activity in a gamma DNA cleavage assay. Thus, structure guided redesign of the catalytic/metal binding site of Cfr10I, provides novel experimental evidence to suggest that spatial rather than sequence conservation plays the dominant role in the formation of restriction enzyme active sites. |

Abstract: Type IIS restriction endonucleases recognize asymmetric DNA sequences and cleave both DNA strands at fixed positions downstream of the recognition site. The restriction endonuclease BpuJI recognizes the asymmetric sequence 5'-CCCGT; however, it cuts at multiple sites in the vicinity of the target sequence. BpuJI consists of two physically separate domains, with catalytic and dimerization functions in the C-terminal domain and DNA recognition functions in the N-terminal domain. Here we report the crystal structure of the BpuJI recognition domain bound to cognate DNA at 1.3-A resolution. This region folds into two winged-helix subdomains, D1 and D2, interspaced by the DL subdomain. The D1 and D2 subdomains of BpuJI share structural similarity with the similar subdomains of the FokI DNA-binding domain; however, their orientations in protein-DNA complexes are different. Recognition of the 5'-CCCGT target sequence is achieved by BpuJI through the major groove contacts of amino acid residues located on both the helix-turn-helix motifs and the N-terminal arm. The role of these interactions in DNA recognition is also corroborated by mutational analysis. |

Abstract: Restriction endonuclease Eco57I from Escherichia coli recognizes asymmetric DNA sequence 5'-CTGAAG and has both restriction (DNA cleavage a short distance away from the recognition site) and modification (methylation) activities residing in a single polypeptide chain. Single crystals of wild-type Eco57I ternary complexes with double-stranded DNA and sinefungin, a stimulator of endonuclease activity, were obtained by the vapor diffusion technique and characterized crystallographically for different variants of the DNA component. The best data for the complex with 25-mer DNA were collected to 4.2-A resolution at 100 K using synchrotron radiation. The crystals are orthorhombic, space group P2(1)2(1)2, with a=164.3, b=293.0, c=71.1 A, and contain two to four copies of the protein in the asymmetric unit. |

Abstract: Rare-cutting restriction enzymes are important tools in genome analysis. We report here the crystal structure of SdaI restriction endonuclease, which is specific for the 8 bp sequence CCTGCA/GG ("/" designates the cleavage site). Unlike orthodox Type IIP enzymes, which are single domain proteins, the SdaI monomer is composed of two structural domains. The N domain contains a classical winged helix-turn-helix (wHTH) DNA binding motif, while the C domain shows a typical restriction endonuclease fold. The active site of SdaI is located within the C domain and represents a variant of the canonical PD-(D/E)XK motif. SdaI determinants of sequence specificity are clustered on the recognition helix of the wHTH motif at the N domain. The modular architecture of SdaI, wherein one domain mediates DNA binding while the other domain is predicted to catalyze hydrolysis, distinguishes SdaI from previously characterized restriction enzymes interacting with symmetric recognition sequences. |

Abstract: The 2.9A resolution crystal structure of apo wild-type GroEL was determined for the first time and represents the reference structure, facilitating the study of structural and functional differences observed in GroEL variants. Until now the crystal structure of the mutant Arg13Gly, Ala126Val GroEL was used for this purpose. We show that, due to the mutations as well as to the presence of a crystallographic symmetry, the ring-ring interface was inaccurately described. Analysis of the present structure allowed the definition of structural elements at this interface, essential for understanding the inter-ring allosteric signal transmission. We also show unambiguously that there is no ATP-induced 102 degrees rotation of the apical domain helix I around its helical axis, as previously assumed in the crystal structure of the (GroEL-KMgATP)(14) complex, and analyze the apical domain movements. These results enabled us to compare our structure with other GroEL crystal structures already published, allowing us to suggest a new route through which the allosteric signal for negative cooperativity propagates within the molecule. The proposed mechanism, supported by known mutagenesis data, underlines the importance of the switching of salt bridges. |

Abstract: Restricion endonuclease Ecl18kI is specific for the sequence /CCNGG and cleaves it before the outer C to generate 5 nt 5'-overhangs. It has been suggested that Ecl18kI is evolutionarily related to NgoMIV, a 6-bp cutter that cleaves the sequence G/CCGGC and leaves 4 nt 5'-overhangs. Here, we report the crystal structure of the Ecl18kI-DNA complex at 1.7 A resolution and compare it with the known structure of the NgoMIV-DNA complex. We find that Ecl18kI flips both central nucleotides within the CCNGG sequence and buries the extruded bases in pockets within the protein. Nucleotide flipping disrupts Watson-Crick base pairing, induces a kink in the DNA and shifts the DNA register by 1 bp, making the distances between scissile phosphates in the Ecl18kI and NgoMIV cocrystal structures nearly identical. Therefore, the two enzymes can use a conserved DNA recognition module, yet recognize different sequences, and form superimposable dimers, yet generate different cleavage patterns. Hence, Ecl18kI is the first example of a restriction endonuclease that flips nucleotides to achieve specificity for its recognition site. |

Abstract: Among all restriction endonucleases known to date, BfiI is unique in cleaving DNA in the absence of metal ions. BfiI represents a different evolutionary lineage of restriction enzymes, as shown by its crystal structure at 1.9-A resolution. The protein consists of two structural domains. The N-terminal catalytic domain is similar to Nuc, an EDTA-resistant nuclease from the phospholipase D superfamily. The C-terminal DNA-binding domain of BfiI exhibits a beta-barrel-like structure very similar to the effector DNA-binding domain of the Mg(2+)-dependent restriction enzyme EcoRII and to the B3-like DNA-binding domain of plant transcription factors. BfiI presumably evolved through domain fusion of a DNA-recognition element to a nonspecific nuclease akin to Nuc and elaborated a mechanism to limit DNA cleavage to a single double-strand break near the specific recognition sequence. The crystal structure suggests that the interdomain linker may act as an autoinhibitor controlling BfiI catalytic activity in the absence of a specific DNA sequence. A psi-blast search identified a BfiI homologue in a Mesorhizobium sp. BNC1 bacteria strain, a plant symbiont isolated from an EDTA-rich environment. |

Abstract: DNA base flipping is an important mechanism in molecular enzymology, but its study is limited by the lack of an accessible and reliable diagnostic technique. A series of crystalline complexes of a DNA methyltransferase, M.HhaI, and its cognate DNA, in which a fluorescent nucleobase analogue, 2-aminopurine (AP), occupies defined positions with respect the target flipped base, have been prepared and their structures determined at higher than 2 A resolution. From time-resolved fluorescence measurements of these single crystals, we have established that the fluorescence decay function of AP shows a pronounced, characteristic response to base flipping: the loss of the very short (approximately 100 ps) decay component and the large increase in the amplitude of the long (approximately 10 ns) component. When AP is positioned at sites other than the target site, this response is not seen. Most significantly, we have shown that the same clear response is apparent when M.HhaI complexes with DNA in solution, giving an unambiguous signal of base flipping. Analysis of the AP fluorescence decay function reveals conformational heterogeneity in the DNA-enzyme complexes that cannot be discerned from the present X-ray structures. |
