Definition: A family of DNA repair enzymes that recognize damaged nucleotide bases and remove them by hydrolyzing the N-glycosidic bond that attaches them to the sugar backbone of the DNA molecule. The process called BASE EXCISION REPAIR can be completed by a DNA-(APURINIC OR APYRIMIDINIC SITE) LYASE which excises the remaining RIBOSE sugar from the DNA.
Other names Glycosylases, DNA; Glycosylase, Methylpurine DNA; Glycosylase, DNA; DNA N glycosidase; DNA Glycosylase, Methylpurine; Methylpurine DNA Glycosylase; DNA Glycosylase; DNA N-glycosidase
