Deoxycytidine monophosphate deaminase in Acetabularia: properties and regulation in the early generative phase.
The occurrence of a dCMP deaminase in Acetabularia mediterranea has been demonstrated. The enzyme which is found in a particulate fraction is substantially stimulated by the addition of dCTP. The activity of the enzyme is increased at the beginning of the generative phase in nucleate as well as in anucleate cells. This regulation is due to de novo synthesis of the enzyme. By means of inhibitor studies, it has been shown that the enzyme is translated on 70S ribosomes of and coced for in cell organelles.
