Protein
Endonuclease III
Gene
nth, RP746
Organism
Rickettsia prowazekii (strain Madrid E)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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 By similarity.UniRule annotation

Catalytic activityi

The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.UniRule annotation

Cofactori

Binds 1 4Fe-4S cluster By similarity.UniRule annotation
