ID 3.6.1.65 DE (d)CTP diphosphatase. AN (d)CTP diphosphohydrolase. AN (d)CTP pyrophosphohydrolase. CA (1) CTP + H2O = CMP + diphosphate + H(+). CA (2) dCTP + H2O = dCMP + diphosphate + H(+). CC -!- The enzyme, characterized from the bacterium Escherichia coli, CC is specific for the pyrimidine nucleotides CTP and dCTP. CC -!- It also acts on 5-methyl-dCTP, 5-hydroxy-dCTP and 8-hydroxy-dGTP. DR P77788, NUDG_ECOLI ; //
