Protein

Endonuclease 8

Gene
nei, SL1344_0710
Organism
Salmonella typhimurium (strain SL1344)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. Acts as DNA glycosylase that recognizes and removes damaged bases. Has a preference for oxidized pyrimidines, such as thymine glycol, 5,6-dihydrouracil and 5,6-dihydrothymine. Has AP (apurinic/apyrimidinic) lyase activity and introduces nicks in the DNA strand. Cleaves the DNA backbone by beta-delta elimination to generate a single-strand break at the site of the removed base with both 3'- and 5'-phosphates By similarity.UniRule annotation

Catalytic activityi

Removes damaged bases from DNA, leaving an abasic site.UniRule annotation
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 zinc ion per subunit By similarity.UniRule annotation
