CC -!- FUNCTION: DNA glycosylase with broad substrate specificity. Can remove
CC uracil from double-stranded DNA containing either a U/G, U/A, U/C or
CC U/T base pair (PubMed:12000829, PubMed:17870091, PubMed:24838246). Can
CC also excise hypoxanthine from double-stranded DNA containing G/I, T/I,
CC and A/I base pairs, xanthine from both double-stranded and single
CC stranded DNA, thymine from G/T mismatched DNA, 5'-hydroxymethyluracil
CC and 5'-fluorouracil (PubMed:17870091, PubMed:24838246).
CC {ECO:0000269|PubMed:12000829, ECO:0000269|PubMed:17870091,
CC ECO:0000269|PubMed:24838246}.
CC -!- SIMILARITY: Belongs to the uracil-DNA glycosylase (UDG) superfamily.
CC Type 5 (UDGb) family. {ECO:0000305}.
