Enzyme Commission Primary Name: arginine N-succinyltransferase
Enzyme Commission Synonyms: arginine succinyltransferase, AstA, arginine and ornithine N2-succinyltransferase, AOST, AST, succinyl-CoA:L-arginine 2-N-succinyltransferase
Enzyme Commission Summary:
Also acts on L-ornithine. This is the first enzyme in the arginine succinyltransferase (AST) pathway for the catabolism of arginine [Vander88]. This pathway converts the carbon skeleton of arginine into glutamate, with the concomitant production of ammonia and conversion of succinyl-CoA into succinate and CoA. The five enzymes involved in this pathway are EC 184.108.40.206 (arginine N-succinyltransferase), EC 220.127.116.11 (N-succinylarginine dihydrolase), EC 18.104.22.168 (succinylornithine transaminase), EC 22.214.171.124 (succinylglutamate-semialdehyde dehydrogenase) and EC 126.96.36.199 (succinylglutamate desuccinylase) [Vander85, Cunin86].
