KEGG ENZYME: 2.1.3.9

ENZYME: 2.1.3.9

Entry

EC 2.1.3.9                  Enzyme

Name

N-acetylornithine carbamoyltransferase;
acetylornithine transcarbamylase;
N-acetylornithine transcarbamylase;
AOTC;
carbamoyl-phosphate:2-N-acetyl-L-ornithine carbamoyltransferase;
AOTCase

Class

Transferases;
Transferring one-carbon groups;
Carboxy- and carbamoyltransferases

Sysname

carbamoyl-phosphate:N2-acetyl-L-ornithine carbamoyltransferase

Reaction(IUBMB)

carbamoyl phosphate + N2-acetyl-L-ornithine = phosphate + N-acetyl-L-citrulline [RN:R07245]

Reaction(KEGG)

R07245

Substrate

carbamoyl phosphate [CPD:C00169];
N2-acetyl-L-ornithine [CPD:C00437]

Product

phosphate [CPD:C00009];
N-acetyl-L-citrulline [CPD:C15532]

Comment

Differs from EC 2.1.3.3, ornithine carbamoyltransferase. This enzyme replaces EC 2.1.3.3 in the canonic arginine biosynthetic pathway of several Eubacteria and has no catalytic activity with L-ornithine as substrate.
