UvrD/REP helicase; KEGG: mmo:MMOB4890 1.4e-141 pcrA1; ATP-dependent DNA helicase K03657; COG: COG0210 Superfamily I DNA and RNA helicases; Psort location: Cytoplasmic, score: 8.87.

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 [...]

tRNA (5-methylaminomethyl-2-thiouridylate)-methyltransferase; Catalyzes the 2-thiolation of uridine at the wobble position (U34) of tRNA, leading to the formation of s(2)U34.

DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...]

KEGG: ctc:CTC00579 2.8e-127 sbcC; exonuclease sbcC K03546; COG: COG0419 ATPase involved in DNA repair; Psort location: Extracellular, score: 7.62.

RecA protein; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage; Belongs to the RecA family.

Exonuclease SbcCD, D subunit; SbcCD cleaves DNA hairpin structures. These structures can inhibit DNA replication and are intermediates in certain DNA recombination reactions. The complex acts as a 3'->5' double strand exonuclease that can open hairpins. It also has a 5' single-strand endonuclease activity; Belongs to the SbcD family.

ROK family protein; KEGG: bha:BH0797 1.7e-58 glucose kinase K00845; COG: COG1940 Transcriptional regulator/sugar kinase; Psort location: Cytoplasmic, score: 9.98.
