== Function ==

[[http://www.uniprot.org/uniprot/FPG_ECOLI FPG_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 purines, such as 7,8-dihydro-8-oxoguanine (8-oxoG) and its derivatives such as guanidinohydantoin:C and spiroiminodihydantoin:C, however it also acts on thymine glycol:G, 5,6-dihydrouracil:G and 5-hydroxyuracil:G. 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. Cleaves ssDNA containing an AP site.<ref>PMID:1689309</ref> <ref>PMID:20031487</ref>
