Exodeoxyribonuclease I.
based on mapping to UniProt P04995
Exonucleolytic cleavage in the 3'- to 5'-direction to yield nucleoside 5'-phosphates.
-!- Preference for single-stranded DNA. -!- The Escherichia coli enzyme hydrolyzes glucosylated DNA. -!- Similar enzymes; mammalian DNase III, exonuclease IV, T2- and T4-induced exodeoxyribonucleases. -!- Formerly EC 3.1.4.25.
