CC -!- FUNCTION: Excises ethenocytosine and uracil, which can arise by
CC alkylation or deamination of cytosine, respectively, from the
CC corresponding mispairs with guanine in ds-DNA. It is capable of
CC hydrolyzing the carbon-nitrogen bond between the sugar-phosphate
CC backbone of the DNA and the mispaired base. The complementary strand
CC guanine functions in substrate recognition. Required for DNA damage
CC lesion repair in stationary-phase cells. {ECO:0000255|HAMAP-
CC Rule:MF_01956}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Specifically hydrolyzes mismatched double-stranded DNA and
CC polynucleotides, releasing free uracil.; EC=3.2.2.28;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01956};
CC -!- SUBUNIT: Binds DNA as a monomer. {ECO:0000255|HAMAP-Rule:MF_01956}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01956}.
CC -!- SIMILARITY: Belongs to the uracil-DNA glycosylase (UDG) superfamily.
CC TDG/mug family. {ECO:0000255|HAMAP-Rule:MF_01956}.
