Alpha-ketoglutaric semialdehyde dehydrogenase 1

UniProtKB accession:  Q1JUP4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the NAD(P)(+)-dependent oxidation of alpha-ketoglutaric semialdehyde (alphaKGSA) to alpha-ketoglutarate. Is involved in a degradation pathway of L-arabinose that allows A.brasilense to grow on L-arabinose as a sole carbon source. Prefers NAD(+) to NADP(+) as a cosubstrate. Displays broad substrate specificity: exhibits the highest activity with alphaKGSA and succinic semialdehyde as substrates, but to a lesser extent, is also active with glutaraldehyde, benzaldehyde, and a number of aldehydes from C3 to C8.
