| - | [ | + | [https://www.uniprot.org/uniprot/VSR_ECOLI VSR_ECOLI] Deamination of 5-methylcytosine in DNA results in T/G mismatches. If unrepaired, these mismatches can lead to C-to-C transition mutations. The very short patch (VSP) repair process in E.coli counteracts the mutagenic process by repairing the mismatches in favor of the G-containing strand. This enzyme is an endonuclease that nicks double-stranded DNA within the sequence CT(AT)GN or NT(AT)GG next to the thymidine residue that is mismatched to 2'-deoxyguanosine. The incision is mismatch-dependent and strand-specific. |
