MSH: A family of enzymes that catalyze the exonucleolytic cleavage of DNA. It includes members of the class EC 3.1.11 that produce 5'-phosphomonoesters as cleavage products.,CSP: family of enzymes that catalyze the exonucleolytic cleavage of DNA; includes members of the class EC 3.1.11 that produce 5'-phosphomonoesters as cleavage products.,NCI: Enzymes that sequentially catalyze the hydrolysis of single nucleotides from the end of a DNA chain. These enzymes play an important role during DNA repair.
