Accepted name: arginine N-succinyltransferase
Reaction: succinyl-CoA + L-arginine = CoA + N2-succinyl-L-arginine

Other name(s): arginine succinyltransferase; AstA; arginine and ornithine N2-succinyltransferase; AOST; AST; succinyl-CoA:L-arginine 2-N-succinyltransferase
Systematic name: succinyl-CoA:L-arginine N2-succinyltransferase
Comments: Also acts on L-ornithine. This is the first enzyme in the arginine succinyltransferase (AST) pathway for the catabolism of arginine [1]. 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) [2,6].
