== Function ==
[https://www.uniprot.org/uniprot/MUTY_ECOLI MUTY_ECOLI] Adenine glycosylase active on G-A mispairs. MutY also corrects error-prone DNA synthesis past GO lesions which are due to the oxidatively damaged form of guanine: 7,8-dihydro-8-oxoguanine (8-oxo-dGTP).

== Publication Abstract from PubMed ==
The DNA glycosylase MutY, which is a member of the Helix-hairpin-Helix (HhH) DNA glycosylase superfamily, excises adenine from mispairs with 8-oxoguanine and guanine. High-resolution crystal structures of the MutY catalytic core (cMutY), the complex with bound adenine, and designed mutants reveal the basis for adenine specificity and glycosyl bond cleavage chemistry. The two cMutY helical domains form a positively-charged groove with the adenine-specific pocket at their interface. The Watson-Crick hydrogen bond partners of the bound adenine are substituted by protein atoms, confirming a nucleotide flipping mechanism, and supporting a specific DNA binding orientation by MutY and structurally related DNA glycosylases.
