Deoxyribonuclease IV is a type of 5'-->3' exonuclease primarily found in mammalian tissues. The approximate molecular weight is 42,000 Dalton (unit) and it requires a metal ion as a cofactor. DNase IV degrades the nucleotide from 5' to 3' direction by attacking 5'-terminal ends of Deoxyribonucleotide. This enzyme was discovered that it is essential for repair of a AP site throughout the nucleotide excision-repair pathway.
