Exodeoxyribonuclease, large subunit; Bidirectionally degrades single-stranded DNA into large acid- insoluble oligonucleotides, which are then degraded further into small acid-soluble oligonucleotides; Belongs to the XseA family.

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 [...]

single-stranded-DNA-specific exonuclease RecJ; Identified by similarity to GP:147550; match to protein family HMM PF01368; match to protein family HMM PF02272; match to protein family HMM TIGR00644.

Holliday junction DNA helicase RuvB; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing.

Holliday junction DNA helicase RuvA; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing. RuvA stimulates, in the presence of DNA, the weak ATPase activity of RuvB.

DNA repair protein RecO; Involved in DNA repair and RecF pathway recombination. Involved in pilin antigenic variation (By similarity).

ATP-dependent DNA helicase RecQ; Identified by similarity to GP:148221; match to protein family HMM PF00270; match to protein family HMM PF00271; match to protein family HMM PF00570; match to protein family HMM TIGR00614; match to protein family HMM TIGR01389.

Hypothetical protein; Identified by Glimmer2; putative; Belongs to the peptidase S24 family.

DNA repair protein RadA; DNA-dependent ATPase involved in processing of recombination intermediates, plays a role in repairing DNA breaks. Stimulates the branch migration of RecA-mediated strand transfer reactions, allowing the 3' invading strand to extend heteroduplex DNA faster. Binds ssDNA in the presence of ADP but not other nucleotides, has ATPase activity that is stimulated by ssDNA and various branched DNA structures, but inhibited by SSB. Does not have RecA's homology-searching function.
