Putrescine carbamoyltransferase

In enzymology, a putrescine carbamoyltransferase (EC 2.1.3.6) is an enzyme that catalyzes the chemical reaction

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.
