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. |
