In contrast to the deoxycytidylate deaminase from animal tissues, the deaminase induced by T2r+ infection of Escherichia coli does not deaminate 5-hydroxymethyldeoxycytidylate. The depletion of this essential T-even phage deoxyribonucleic acid precursor is thus prevented. Although there is an apparent difference in substrate specificity between these deoxycytidylate deaminases, their ability to regulate the formation of deoxyuridylate by feedback control is quite similar.
