2.1.3.6 |
Accepted name: |
putrescine carbamoyltransferase |
Reaction: |
carbamoyl phosphate + putrescine = phosphate + N-carbamoylputrescine |
Glossary: |
putrescine = butane-1,4-diamine |
Other name(s): |
PTCase; putrescine synthase; putrescine transcarbamylase |
Systematic name: |
carbamoyl-phosphate:putrescine carbamoyltransferase |
Comments: |
The plant enzyme also catalyses the reactions of EC 2.1.3.3 ornithine carbamoyltransferase, EC 2.7.2.2 carbamate kinase and EC 3.5.3.12 agmatine deiminase, thus acting as putrescine synthase, converting agmatine [(4-aminobutyl)guanidine] and ornithine into putrescine and citrulline, respectively. |
