IntEnz Enzyme Nomenclature


Accepted name:
succinate-semialdehyde dehydrogenase (NADP+)
Other names:
succinic semialdehyde dehydrogenase (NADP+)
succinyl semialdehyde dehydrogenase (NADP+)
succinate semialdehyde:NADP+ oxidoreductase
NADP-dependent succinate-semialdehyde dehydrogenase
Systematic name:
succinate-semialdehyde:NADP+ oxidoreductase



This enzyme participates in the degradation of glutamate and 4-aminobutyrate. It is similar to EC [succinate-semialdehyde dehydrogenase (NAD+)], and EC [succinate-semialdehyde dehydrogenase (NAD(P)+)], but is specific for NADP+. The enzyme from Escherichia coli is 20-fold more active with NADP+ than NAD+ [2].
