DNA glycosylase (DG) are enzymes which remove damaged DNA bases by flipping them out of the double helix followed by their cleavage. Monofunctional DG have only glycosylase activity; bifunctional DG also act as lysates; ADG, UDG, TDG remove adenine, uracil, thymine from DNA. ADG is also called MutY. Smug1 is a single-strand selective monofunctional UDG. OxDG recognize oxidized bases. The human 8-oxoguanine GD is named hOgg1. AlkDG recognize methylated adenine. Formamidopyrimidine DG (FPG) or MutM removes oxidized purines from damaged DNA. More about FPG in Fpg Nei Protein Family and Fpg Nei Protein Superfamily.
