Thus, the two substrates of this enzyme are carbamoyl phosphate and putrescine, whereas its two products are phosphate and N-carbamoylputrescine.
This enzyme belongs to the family of transferases that transfer one-carbon groups, specifically the carboxy- and carbamoyltransferases. The systematic name of this enzyme class is carbamoyl-phosphate:putrescine carbamoyltransferase. Other names in common use include PTCase, putrescine synthase, and putrescine transcarbamylase.
