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 (arginine N-succinyltransferase), EC (N-succinylarginine dihydrolase), EC (succinylornithine transaminase), EC (succinylglutamate-semialdehyde dehydrogenase) and EC (succinylglutamate desuccinylase) [Vander85, Cunin86].
