Notes

[back to top]


YbaZ is homologous to methylated-DNA--protein-cysteine methyltransferases Ada and Ogt, but lacks the active site cysteine. YbaZ binds O(6)-alkylguanine residues in DNA and blocks alkyltransferase action; YbaZ does not remove methyl groups from O(6)-methylguanine-containing DNA nor does it have glycosylase or endonuclease activity (Margison, 2007). YbaZ preferentially binds DNA with an abasic site, has base-flipping activity, and binds HelD (Chen, 2008).[4]
