Comments [?]

Function Catalyzes the transfer of the carbamoyl group from carbamoyl phosphate to the delta-amino group of N(2)-acetyl-L-ornithine to produce N(2)-acetyl-L-citrulline. This is a step in an alternative arginine biosynthesis pathway.
Catalytic activity RHEA:18609: carbamoyl phosphate + N(2)-acetyl-L-ornithine = H(+) + N(2)-acetyl-L-citrulline + phosphate
EC 2.1.3.9
PhysiologicalDirection=left-to-right (RHEA:18610)
Pathway Amino-acid biosynthesis; L-arginine biosynthesis.
Subunit Homotrimer.
Subcellular location Cytoplasm.
Similarity Belongs to the aspartate/ornithine carbamoyltransferase superfamily. AOTCase family.
