== Function ==
[https://www.uniprot.org/uniprot/MUG_ECOLI MUG_ECOLI] 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.<ref>PMID:8878487</ref> <ref>PMID:12668677</ref>
