EC 2.1.3.3 Details
show Brenda entryEC number
2.1.3.3
Accepted name
ornithine carbamoyltransferase
Reaction
carbamoyl phosphate + L-ornithine = phosphate + L-citrulline
Other name(s)
citrulline phosphorylase,
ornithine transcarbamylase,
OTC,
carbamylphosphate-ornithine transcarbamylase,
L-ornithine carbamoyltransferase,
L-ornithine carbamyltransferase,
L-ornithine transcarbamylase,
ornithine carbamyltransferase
Systematic name
carbamoyl-phosphate:L-ornithine carbamoyltransferase
CAS registry number
9001-69-8
Comment
The plant enzyme also catalyses the reactions of EC 2.1.3.6 putrescine 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.
