GQS_05880 | COG1239 Mg-chelatase subunit ChlI. (637 aa) | ||||
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. (238 aa) | ||||
GQS_05885 | COG1429 Cobalamin biosynthesis protein CobN and related Mg-chelatases. (1252 aa) |
