Deoxyribodipyrimidine endonucleosidase

Deoxyribodipyrimidine endonucleosidase (EC 3.2.2.17, pyrimidine dimer DNA-glycosylase, endonuclease V, deoxyribonucleate pyrimidine dimer glycosidase, pyrimidine dimer DNA glycosylase, T4-induced UV endonuclease, PD-DNA glycosylase) is an enzyme with systematic name deoxy-D-ribocyclobutadipyrimidine polynucleotidodeoxyribohydrolase. This enzyme catalyses the following chemical reaction

Cleaves the N-glycosidic bond between the 5'-pyrimidine residue in cyclobutadipyrimidine (in DNA) and the corresponding deoxy-D-ribose residue
