CC   -!- FUNCTION: Excises uracil residues from the DNA which can arise as a
CC       result of misincorporation of dUMP residues by DNA polymerase or due to
CC       deamination of cytosine. {ECO:0000255|HAMAP-Rule:MF_00148}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolyzes single-stranded DNA or mismatched double-stranded
CC         DNA and polynucleotides, releasing free uracil.; EC=3.2.2.27;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00148};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00148}.
CC   -!- SIMILARITY: Belongs to the uracil-DNA glycosylase (UDG) superfamily.
CC       UNG family. {ECO:0000255|HAMAP-Rule:MF_00148}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAK99859.1; Type=Erroneous initiation; Evidence={ECO:0000305};
