Function 
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.
-  Adenine DNA glycosylase is also called MutY.
 
-  Thymine DNA glycosylase removes thymine moieties from mismatched G/T, C/T and T/T.
 
-  Smug1 is a single-strand selective monofunctional UDG. 
 
-  8-oxoguanine DNA glycosylase recognize oxidized bases.
 
-   Human 8-oxoguanine GD is named hOgg1.  See details on Ogg1 in 8-Oxoguanine Glycosylase.
 
-   Methyladenine DNA glycosylase recognize methylated adenine; for details see Alka1. 
 
-  Formamidopyrimidine DG (FPG) or MutM or Fapy-DNA glycosylase removes oxidized purines from damaged DNA.  More about FPG in
