This enzyme belongs to the family of lyases, specifically the class of phosphorus-oxygen lyases. The systematic name of this enzyme class is CTP diphosphate-lyase (cyclizing; 3â²,5â²-cyclic-CMP-forming). Other names in common use include 3',5'-cyclic-CMP synthase, cytidylyl cyclase, cytidyl cyclase, and CTP diphosphate-lyase (cyclizing).
