Deoxyribodipyrimidine endonucleosidase

Deoxyribodipyrimidine endonucleosidase (, "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
The only family of enzymes known to have this activity is represented by a phage T4 protein. This family also has AP lyase activity against the AP site produced by this reaction.
