N-succinylornithine carbamoyltransferase
N-succinylornithine carbamoyltransferase (EC 2.1.3.11, succinylornithine transcarbamylase, N-succinyl-L-ornithine transcarbamylase, SOTCase) is an enzyme with systematic name carbamoyl phosphate:N2-succinyl-L-ornithine carbamoyltransferase.[1][2] This enzyme catalyses the following chemical reaction
- carbamoyl phosphate + N2-succinyl-L-ornithine phosphate + N-succinyl-L-citrulline
