Accepted name: 5′-deoxynucleotidase
Reaction: a 2′-deoxyribonucleoside 5′-monophosphate + H2O = a 2′-deoxyribonucleoside + phosphate
Other name(s): yfbR (gene name)
Systematic name: 2′-deoxyribonucleoside 5′-monophosphate phosphohydrolase
Comments: The enzyme, characterized from the bacterium Escherichia coli, shows strict specificity towards deoxyribonucleoside 5′-monophosphates and does not dephosphorylate 5′-ribonucleotides or ribonucleoside 3′-monophosphates. A divalent metal cation is required for activity, with cobalt providing the highest activity.
