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.
  
• 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.
  
• AlkDG 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
