This enzyme belongs to the family of transferases that transfer one-carbon groups, specifically the carboxy- and carbamoyltransferases. The systematic name of this enzyme class is carbamoyl-phosphate:N2-acetyl-L-ornithine carbamoyltransferase. Other names in common use include acetylornithine transcarbamylase, N-acetylornithine transcarbamylase, AOTC, and carbamoyl-phosphate:2-N-acetyl-L-ornithine carbamoyltransferase.
