Newly detected families to hint at further functional details.COG, COG and Replic_Relax (PF) commonly take place within a fusion with HTH DNAbinding domains, which suggests their part in transcription regulation.DUF (PF) and DUF (PF) are frequently present in proteins encoding an ATPase domain.Furthermore, DUF appears in a range of domain architectures, which includes fusions with helicases, TF domains, protein kinases and MTases.Details of identification of new households are summarized in Supplementary Table S.One particular should note that only two of them have been assigned towards the PD(DE)XK superfamily with MetaBASIC scores above self-assurance threshold of .Structure analysis A complete evaluation of the identified structures enables us to improved comprehend how the PD(DE)XK fold adapt to unique functions.The structural analyses are crucial to additional detection and PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21570513 classificationTable .One hundred and twentyone groups of proteins retaining PD(DE)XK nuclease foldPfam, COGKOG,PDB structureNo.Name Reference tofold assignmentBiological functionTaxonomyHGTsVirusesBacteriaArchaeaNaeIPF ev Variety II Restriction Endonuclease Form II Restriction Endonuclease Bacteria (Bacillus Clostridium, Bacteroidetes) BacteriaType II Restriction Endonuclease Eukaryota Detailed distribution Bacteria (proteobacteria, Actinobacteria) Bacteria (largely Neisseria) Bacteria Bacteria (Cyanobacteria, Bacillus Clostridium,proteobacteria) Bacteria BacteriaBglIdmuHpaIIPFNew New Type II Restriction Endonuclease Variety II Restriction Endonuclease NgoBV, NlaIVPFType II Restriction Endonuclease ScaIPFLlaMI, ScrFIPFPvuIIPF kskType II Restriction Endonuclease XamIPFType II Restriction Endonuclease Kind II Restriction Endonuclease Form II Restriction Endonuclease {} {}XhoIPFDeinococcus maricopensis sequence is found in a clade with Roseobacteriales (aproteobacteria) Actinomycetales.The Roseobacteriales clade locates within a Actinomycetales tree.Only four Lodenafil Metabolic Enzyme/Protease sequences from distant taxa Bacillus atrophaeus (Bacilli), Microcoleus (Oscillatoriales), Deinococcus deserti (Deinococci) recommend a HGT.Streotibacillus moniliformis (Fusobacteriales) types a clade with Sulfurimonas denitrificans (Campylobacteriales).Bacillus thuringiensis (Bacillales) groups with Flexibacter tractuosus (Cytophagales).Single sequences of Fusobacteria, eproteobacteria, bproteobacteria and gproteobacteria.Multiple transfers, animal related bacteria.Single representatives of Spirochaetes, Fusobacteria, Tenericutes, eproteobacteria, Clostridia, Bacilli.Several transfers.Ecologically and taxonomically unrelated bacteria from Bacilli, Proteobacteria, Cyanobacteria, Bacterioidetes.One particular clade grouping Lachnospiraceae bacterium (Clostridiales), Lactococcus lactis subsp.cremoris (Lactobacillales), Prochlorococcus marinus (Cyanobacteria), Vibrio parahaemolyticus (gproteobacteria).Meiothermus ruber (Thermales), Bacteroides cellulosilyticus (Bacteroidales) and Arthrospira maxima (Burkholderiales) are single representatives of corresponding taxa suggesting a transfer occasion from Enterobacteriales.Patchy distribution such as a Haloarcheon Halogeometricum borinquense grouping with great help within a bacterial clade.Leptospirillum rubarum and Actinobacteria within a Proteobacteria clade.
