Protein

G/U mismatch-specific DNA glycosylase

Gene

mug

Organism
Shigella sonnei (strain Ss046)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Excises ethenocytosine and uracil, which can arise by alkylation or deamination of cytosine, respectively, from the corresponding mispairs with guanine in ds-DNA. It is capable of hydrolyzing the carbon-nitrogen bond between the sugar-phosphate backbone of the DNA and the mispaired base. The complementary strand guanine functions in substrate recognition. Required for DNA damage lesion repair in stationary-phase cells.UniRule annotation

Catalytic activityi

Specifically hydrolyzes mismatched double-stranded DNA and polynucleotides, releasing free uracil.UniRule annotation
