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}.
