Deoxyribodipyrimidine endonucleosidase
Deoxyribodipyrimidine endonucleosidase 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.
