nth | Endonuclease III; DNA repair enzyme that has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases various damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'- phosphate. (227 aa) | ||||
Sps_02352 | A/G-specific DNA-adenine glycosylase; Adenine glycosylase active on G-A mispairs. (364 aa) | ||||
ligA | DNA ligase, NAD-dependent; DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA. (682 aa) | ||||
ruvA | Holliday junction DNA helicase subunit 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. (205 aa) | ||||
Sps_00236 | Transcriptional accessory protein; PFAM: Tex-like protein N-terminal domain; Holliday-junction resolvase-like of SPT6; S1 RNA binding domain; Helix-hairpin-helix motif. (820 aa) | ||||
uvrC | Excinuclease ABC subunit C; The UvrABC repair system catalyzes the recognition and processing of DNA lesions. UvrC both incises the 5' and 3' sides of the lesion. The N-terminal half is responsible for the 3' incision and the C-terminal half is responsible for the 5' incision. (609 aa) | ||||
Sps_01862 | PFAM: Helix-hairpin-helix motif; TIGRFAM: competence protein ComEA helix-hairpin-helix repeat region; comEA protein. (105 aa) |
