17-245 2.40e-87

Endonuclease_V, a DNA repair enzyme that initiates repair of nitrosative deaminated purine bases; Endonuclease_V (EndoV) is an enzyme that can initiate repair of all possible deaminated DNA bases. EndoV cleaves the DNA strand containing lesions at the second phosphodiester bond 3' to the lesion using Mg2+ as a cofactor. EndoV homologs are conserved throughout all domains of life from bacteria to humans. EndoV is encoded by the nfi gene and nfi null mutant mice have a phenotype prone to cancer. The ability of endonuclease V to recognize mismatches and abnormal replicative DNA structures suggests that the enzyme plays an important role in DNA metabolism. The details of downstream processing for the EndoV pathway remain unknown.
