BsiY I, a novel thermophilic restriction endonuclease that recognizes 5' CCNNNNNNNGG 3' and the discovery of a wrongly sequenced site in pACYC177.

ABSTRACT: A new type II restriction endonuclease designated BsiY I has been purified from a thermophilic soil Bacillus stearothermophilus strain. This enzyme recognizes and cleaves the highly degenerate sequence 5' CCNNNNN!NNGG 3'. During the identification of the recognition sequence of BsiY I, we discovered that there should be five G nucleotides instead of four at position 1227-1230 of the plasmid pACYC177.

Restriction endonuclease MvaI is a monomer that recognizes its target sequence asymmetrically.

Project description:Restriction endonuclease MvaI recognizes the sequence CC/WGG (W stands for A or T, '/' designates the cleavage site) and generates products with single nucleotide 5'-overhangs. The enzyme has been noted for its tolerance towards DNA modifications. Here, we report a biochemical characterization and crystal structures of MvaI in an apo-form and in a complex with target DNA at 1.5 A resolution. Our results show that MvaI is a monomer and recognizes its pseudosymmetric target sequence asymmetrically. The enzyme consists of two lobes. The catalytic lobe anchors the active site residues Glu36, Asp50, Glu55 and Lys57 and contacts the bases from the minor grove side. The recognition lobe mediates all major grove interactions with the bases. The enzyme in the crystal is bound to the strand with T at the center of the recognition sequence. The crystal structure with calcium ions and DNA mimics the prereactive state. MvaI shows structural similarities to BcnI, which cleaves the related sequence CC/SGG and to MutH enzyme, which is a component of the DNA repair machinery, and nicks one DNA strand instead of making a double-strand break.

Unusual target site disruption by the rare-cutting HNH restriction endonuclease PacI.

Project description:The crystal structure of the rare-cutting HNH restriction endonuclease PacI in complex with its eight-base-pair target recognition sequence 5'-TTAATTAA-3' has been determined to 1.9 A resolution. The enzyme forms an extended homodimer, with each subunit containing two zinc-bound motifs surrounding a betabetaalpha-metal catalytic site. The latter is unusual in that a tyrosine residue likely initiates strand cleavage. PacI dramatically distorts its target sequence from Watson-Crick duplex DNA base pairing, with every base separated from its original partner. Two bases on each strand are unpaired, four are engaged in noncanonical A:A and T:T base pairs, and the remaining two bases are matched with new Watson-Crick partners. This represents a highly unusual DNA binding mechanism for a restriction endonuclease, and implies that initial recognition of the target site might involve significantly different contacts from those visualized in the DNA-bound cocrystal structures.

Identification of a single HNH active site in type IIS restriction endonuclease Eco31I.

Project description:Type IIS restriction endonuclease Eco31I is a "short-distance cutter", which cleaves DNA strands close to its recognition sequence, 5'-GGTCTC(1/5). Previously, it has been proposed that related endonucleases recognizing a common sequence core GTCTC possess two active sites for cleavage of both strands in the DNA substrate. Here, we present bioinformatic identification and experimental evidence for a single nuclease active site. We identified a short region of homology between Eco31I and HNH nucleases, constructed a three-dimensional model of the putative catalytic domain and validated our predictions by random and site-specific mutagenesis. The restriction mechanism of Eco31I is suggested by analogy to the mechanisms of phage T4 endonuclease VII and homing endonuclease I-PpoI. We propose that residues D311 and N334 coordinate the cofactor. H312 acts as a general base-activating water molecule for the nucleophilic attack. K337 together with R340 and D345 are located in close proximity to the active center and are essential for correct folding of catalytic motif, while D345 together with R264 and D273 could be directly involved in DNA binding. We also predict that the Eco31I catalytic domain contains a putative Zn-binding site, which is essential for its structural integrity. Our results suggest that the HNH-like active site is involved in the cleavage of both strands in the DNA substrate. On the other hand, analysis of site-specific mutants in the region, previously suggested to harbor the second active site, revealed its irrelevance to the nuclease activity. Thus, our data argue against the earlier prediction and indicate the presence of a single conserved active site in type IIS restriction endonucleases that recognize common sequence core GTCTC.

Discovery and genotyping of novel sequence insertions in many sequenced individuals.

Project description:MotivationDespite recent advances in algorithms design to characterize structural variation using high-throughput short read sequencing (HTS) data, characterization of novel sequence insertions longer than the average read length remains a challenging task. This is mainly due to both computational difficulties and the complexities imposed by genomic repeats in generating reliable assemblies to accurately detect both the sequence content and the exact location of such insertions. Additionally, de novo genome assembly algorithms typically require a very high depth of coverage, which may be a limiting factor for most genome studies. Therefore, characterization of novel sequence insertions is not a routine part of most sequencing projects.ResultHere, we present Pamir, a new algorithm to efficiently and accurately discover and genotype novel sequence insertions using either single or multiple genome sequencing datasets. Pamir is able to detect breakpoint locations of the insertions and calculate their zygosity (i.e. heterozygous versus homozygous) by analyzing multiple sequence signatures, matching one-end-anchored sequences to small-scale de novo assemblies of unmapped reads, and conducting strand-aware local assembly. We test the efficacy of Pamir on both simulated and real data, and demonstrate its potential use in accurate and routine identification of novel sequence insertions in genome projects.Availability and implementationPamir is available at https://github.com/vpc-ccg/pamir .Contactfhach@{sfu.ca, prostatecentre.com } or calkan@cs.bilkent.edu.tr.Supplementary informationSupplementary data are available at Bioinformatics online.

Identification of novel restriction endonuclease-like fold families among hypothetical proteins.

Project description:Restriction endonucleases and other nucleic acid cleaving enzymes form a large and extremely diverse superfamily that display little sequence similarity despite retaining a common core fold responsible for cleavage. The lack of significant sequence similarity between protein families makes homology inference a challenging task and hinders new family identification with traditional sequence-based approaches. Using the consensus fold recognition method Meta-BASIC that combines sequence profiles with predicted protein secondary structure, we identify nine new restriction endonuclease-like fold families among previously uncharacterized proteins and predict these proteins to cleave nucleic acid substrates. Application of transitive searches combined with gene neighborhood analysis allow us to confidently link these unknown families to a number of known restriction endonuclease-like structures and thus assign folds to the uncharacterized proteins. Finally, our method identifies a novel restriction endonuclease-like domain in the C-terminus of RecC that is not detected with structure-based searches of the existing PDB database.

Photochemical regulation of restriction endonuclease activity.

Project description:Removal by the light: The photochemical regulation of restriction endonucleases, which are important enzymes in molecular biology, has been investigated. Photolabile protecting groups have been installed on DNA substrates and have been demonstrated to inhibit restriction endonuclease activity until removed by UV light irradiation. Interestingly, these groups do not appear to dramatically affect initial binding of the enzyme to the DNA substrate, but rather prevent recognition of the specific cleavage site.

Cofactor requirement of HpyAV restriction endonuclease.

Project description:BackgroundHelicobacter pylori is the etiologic agent of common gastritis and a risk factor for gastric cancer. It is also one of the richest sources of Type II restriction-modification (R-M) systems in microorganisms.Principal findingsWe have cloned, expressed and purified a new restriction endonuclease HpyAV from H. pylori strain 26695. We determined the HpyAV DNA recognition sequence and cleavage site as CCTTC 6/5. In addition, we found that HpyAV has a unique metal ion requirement: its cleavage activity is higher with transition metal ions than in Mg(++). The special metal ion requirement of HpyAV can be attributed to the presence of a HNH catalytic site similar to ColE9 nuclease instead of the canonical PD-X-D/EXK catalytic site found in many other REases. Site-directed mutagenesis was carried out to verify the catalytic residues of HpyAV. Mutation of the conserved metal-binding Asn311 and His320 to alanine eliminated cleavage activity. HpyAV variant H295A displayed approximately 1% of wt activity.Conclusions/significanceSome HNH-type endonucleases have unique metal ion cofactor requirement for optimal activities. Homology modeling and site-directed mutagenesis confirmed that HpyAV is a member of the HNH nuclease family. The identification of catalytic residues in HpyAV paved the way for further engineering of the metal binding site. A survey of sequenced microbial genomes uncovered 10 putative R-M systems that show high sequence similarity to the HpyAV system, suggesting lateral transfer of a prototypic HpyAV-like R-M system among these microorganisms.

Restriction glycosylases: involvement of endonuclease activities in the restriction process.

Project description:All restriction enzymes examined are phosphodiesterases generating 3΄-OH and 5΄-P ends, but one restriction enzyme (restriction glycosylase) excises unmethylated bases from its recognition sequence. Whether its restriction activity involves endonucleolytic cleavage remains unclear. One report on this enzyme, R.PabI from a hyperthermophile, ascribed the breakage to high temperature while another showed its weak AP lyase activity generates atypical ends. Here, we addressed this issue in mesophiles. We purified R.PabI homologs from Campylobacter coli (R.CcoLI) and Helicobacter pylori (R.HpyAXII) and demonstrated their DNA cleavage, DNA glycosylase and AP lyase activities in vitro at 37°C. The AP lyase activity is more coupled with glycosylase activity in R.CcoLI than in R.PabI. R.CcoLI/R.PabI expression caused restriction of incoming bacteriophage/plasmid DNA and endogenous chromosomal DNA within Escherichia coli at 37°C. The R.PabI-mediated restriction was promoted by AP endonuclease action in vivo or in vitro. These results reveal the role of endonucleolytic DNA cleavage in restriction and yet point to diversity among the endonucleases. The cleaved ends are difficult to repair in vivo, which may indicate their biological significance. These results support generalization of the concept of restriction–modification system to the concept of self-recognizing epigenetic system, which combines any epigenetic labeling and any DNA damaging.

Exploring both sequence detection and restriction endonuclease cleavage kinetics by recognition site via single-molecule microfluidic trapping.

Project description:We demonstrate the feasibility of a single-molecule microfluidic approach to both sequence detection and obtaining kinetic information for restriction endonucleases on dsDNA. In this method, a microfluidic stagnation point flow is designed to trap, hold, and linearize double-stranded (ds) genomic DNA to which a restriction endonuclease has been pre-bound sequence-specifically. By introducing the cofactor magnesium, we determine the binding location of the enzyme by the cleavage process of dsDNA as in optical restriction mapping, however here the DNA need not be immobilized on a surface. We note that no special labeling of the enzyme is required, which makes it simpler than our previous scheme using stagnation point flows for sequence detection. Our accuracy in determining the location of the recognition site is comparable to or better than other single molecule techniques due to the fidelity with which we can control the linearization of the DNA molecules. In addition, since the cleavage process can be followed in real time, information about the cleavage kinetics, and subtle differences in binding and cleavage frequencies among the recognition sites, may also be obtained. Data for the five recognition sites for the type II restriction endonuclease EcoRI on λ-DNA are presented as a model system. While the roles of the varying fluid velocity and tension along the chain backbone on the measured kinetics remain to be determined, we believe this new method holds promise for a broad range of studies of DNA-protein interactions, including the kinetics of other DNA cleavage processes, the dissociation of a restriction enzyme from the cleaved substrate, and other macromolecular cleavage processes.
