ENTRY EC 3.1.11.5
NAME Exodeoxyribonuclease V
E.coli exonuclease V
CLASS Hydrolases
Acting on ester bonds
Exodeoxyribonucleases producing 5'-phosphomonoesters
REACTION Exonucleolytic cleavage (in presence of ATP) in either 5'- to 3'-
or 3'- to 5'-direction to yield 5'-phosphooligonucleotides
SUBSTRATE Deoxyribonucleotide
Double-stranded DNA
Single-stranded DNA
H2O
ATP
PRODUCT 5'-Phosphooligonucleotide
ADP
Orthophosphate
COFACTOR ATP
COMMENT Preference for double-stranded DNA. Possesses DNA-dependent ATPase
activity. Acts endonucleolytically on single-stranded circular
DNA. Similar enzyme: Haemophilus influenzae ATP-dependent DNase.
