Other name(s): succinylglutamic semialdehyde dehydrogenase; N-succinylglutamate 5-semialdehyde dehydrogenase; SGSD; AruD; AstD

Systematic name: N-succinyl-L-glutamate 5-semialdehyde:NAD+ oxidoreductase

Comments: This is the fourth 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 (acetylornithine transaminase), EC (succinylglutamate-semialdehyde dehydrogenase) and EC (succinylglutamate desuccinylase) [3,6].
