CC -!- FUNCTION: Involved in base excision repair of DNA damaged by oxidation
CC or by mutagenic agents. Acts as DNA glycosylase that recognizes and
CC removes damaged bases. Can process efficiently 4,6-diamino-5-
CC formamidopyrimidine (FapyA), 2,6-diamino-4- hydroxy-5-
CC formamidopyrimidine (FapyG) and the further oxidation products of 8-
CC oxoguanine (8-oxoG), such as guanidinohydantoin and
CC spiroiminodihydantoin. Has marginal activity towards 8-oxoG. Has AP
CC (apurinic/apyrimidinic) lyase activity. Cleaves the DNA backbone by
CC beta-delta elimination to generate a single-strand break at the site of
CC the removed base with both 3'- and 5'-phosphates.
