the
chemical reaction
:carbamoyl phosphate + putrescine
phosphate + N-carbamoylputrescine
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.
