Template:STRUCTURE 3fsp

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. See details on Ogg1 in 8-Oxoguanine Glycosylase. AlkDG recognize methylated adenine; for details see Alka1. Formamidopyrimidine DG (FPG) or MutM removes oxidized purines from damaged DNA. More about FPG in
