| + | == Function == | ||
| + | [[http://www.uniprot.org/uniprot/END8_ECOLI END8_ECOLI]] 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. Acts on DNA bubble and 3'-fork structures, suggesting a role in replication-associated DNA repair. 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.<ref>PMID:20031487</ref> | ||
