2'-deoxyribonucleoside 5'-monophosphate phosphohydrolase

a 2'-deoxyribonucleoside 5'-monophosphate + H2O = a 2'-deoxyribonucleoside + phosphate [RN:R10776]

Reaction

2'-deoxyribonucleoside 5'-monophosphate [CPD:C00676];
H2O [CPD:C00001]

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.
