label_lc: class ii dna-(apurinic or apyrimidinic site) endonuclease activity
description: "Catalysis of the hydrolysis of ester linkages immediately 5' to an apurinic/apyrimidinic (AP; also called abasic) site within a deoxyribonucleic acid molecule by creating internal breaks, generating a single-strand break with 5'-deoxyribose phosphate and 3'-hydroxyl ends."
