Superfamily Aspartate/ornithine carbamoyltransferase
Functional Family Ornithine carbamoyltransferase, mitochondrial

Enzyme Information

2.1.3.3
Ornithine carbamoyltransferase.
based on mapping to UniProt P00480
Carbamoyl phosphate + L-ornithine = phosphate + L-citrulline.
-!- The plant enzyme also catalyzes the reactions of EC 2.1.3.6, EC 2.7.2.2 and EC 3.5.3.12, thus acting as putrescine synthase, converting agmatine and ornithine into putrescine and citrulline respectively.
