Excinuclease ABC, B subunit; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. Upon binding of the UvrA(2)B(2) complex to a putative damaged site, the DNA wraps around one UvrB monomer. DNA wrap is dependent on ATP binding by UvrB and probably causes local melting of the DNA helix, facilitating insertion of UvrB beta-hairpin between the DNA strands. Then UvrB probes one DNA strand for the presence of a lesion. If a lesion is found the UvrA subunits dissociate [...]

Exonuclease, DNA polymerase III, epsilon subunit family; KEGG: tte:TTE1398 4.0e-33 polC; DNA polymerase III alpha subunit, the Gram-positive type K03763; COG: COG2176 DNA polymerase III, alpha subunit (gram-positive type); Psort location: Cytoplasmic, score: 8.87.

Excinuclease ABC, A subunit; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrA is an ATPase and a DNA-binding protein. A damage recognition complex composed of 2 UvrA and 2 UvrB subunits scans DNA for abnormalities. When the presence of a lesion has been verified by UvrB, the UvrA molecules dissociate.

KEGG: efa:EF0721 4.4e-186 pcrA; ATP-dependent DNA helicase PcrA K03657; COG: COG0210 Superfamily I DNA and RNA helicases; Psort location: Cytoplasmic, score: 8.87.

DNA-directed DNA polymerase; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity.

HPr(Ser) kinase/phosphatase; Catalyzes the ATP- as well as the pyrophosphate-dependent phosphorylation of a specific serine residue in HPr, a phosphocarrier protein of the phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS). HprK/P also catalyzes the pyrophosphate-producing, inorganic phosphate-dependent dephosphorylation (phosphorolysis) of seryl-phosphorylated HPr (P-Ser-HPr). The two antagonistic activities of HprK/P are regulated by several intracellular metabolites, which change their concentration in response to the absence or presence of rapidly metabolisable car [...]

UvrD/REP helicase; KEGG: cac:CAC1003 6.9e-91 superfamily I DNA helicase (rep-like helicase) K01529; COG: COG0210 Superfamily I DNA and RNA helicases; Psort location: Cytoplasmic, score: 8.87.

DNA mismatch repair domain protein; This protein is involved in the repair of mismatches in DNA. It is required for dam-dependent methyl-directed DNA mismatch repair. May act as a 'molecular matchmaker', a protein that promotes the formation of a stable complex between two or more DNA-binding proteins in an ATP-dependent manner without itself being part of a final effector complex.

DNA polymerase III, beta subunit; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of [...]
