General annotation (Comments)

Function	Catalyzes the NAD-dependent reduction of succinylglutamate semialdehyde into succinylglutamate. Also shows activity with decanal or succinic semialdehyde as the electron donor and NAD as the electron acceptor. No activity is detected with NADP as the electron acceptor. Therefore, is an aldehyde dehydrogenase with broad substrate specificity.
Catalytic activity	N-succinyl-L-glutamate 5-semialdehyde + NAD(+) + H(2)O = N-succinyl-L-glutamate + NADH.
Pathway	Amino-acid degradation; L-arginine degradation via AST pathway; L-glutamate and succinate from L-arginine: step 4/5.
Induction	By nitrogen starvation, and arginine. Induced at stationary phase by sigma S.
Sequence similarities	Belongs to the aldehyde dehydrogenase family. AstD subfamily.
Biophysicochemical properties	Kinetic parameters: KM=91 µM for decanal KM=160 µM for NAD (at pH 8.5) KM=1.72 mM for succinic semialdehyde (at pH 8.5) Vmax=5.0 µmol/min/mg enzyme with decanal as substrate Vmax=0.69 µmol/min/mg enzyme with succinic semialdehyde as substrate
