N2-succinyl-L-arginine iminohydrolase (decarboxylating)

Arginine, N2-acetylarginine and N2-glutamylarginine do not act as substrates [3]. This is the second 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 2.3.1.109 (arginine N-succinyltransferase), EC 3.5.3.23 (N-succinylarginine dihydrolase), EC 2.6.1.81 (succinylornithine transaminase), EC 1.2.1.71 (succinylglutamate semialdehyde dehydrogenase) and EC 3.5.1.96 (succinylglutamate desuccinylase).
