Reaction: Exonucleolytic cleavage in the 5'- to 3'-direction to yield nucleoside 5'-phosphates
Other name(s): lambda exonuclease; phage lambda-induced exonuclease; Escherichia coli exonuclease IV; E. coli exonuclease IV; exodeoxyribonuclease IV; exonuclease IV
Comments: Preference for double-stranded DNA. Does not attack single-strand breaks. Formerly EC 22.214.171.124.
