DNA Glycosylases MeSH Descriptor Data 2023

MeSH Heading
DNA Glycosylases
Tree Number(s)
Unique ID
RDF Unique Identifier
Scope Note
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.
Entry Term(s)
