Enzyme Information

L-glutamate gamma-semialdehyde dehydrogenase.
based on mapping to UniProt Q8CHT0
L-glutamate 5-semialdehyde + NAD(+) + H(2)O = L-glutamate + NADH.
-!- This enzyme catalyzes the irreversible oxidation of glutamate-gamma- semialdehyde to glutamate as part of the proline degradation pathway. -!- (S)-1-pyrroline-5-carboxylate, the product of the first enzyme of the pathway (EC 1.5.5.2) is in spontaneous equilibrium with its tautomer L-glutamate gamma-semialdehyde. -!- In many bacterial species, both activities are carried out by a single bifunctional enzyme. -!- The enzyme can also oxidize other 1-pyrrolines, e.g. 3-hydroxy-1- pyrroline-5-carboxylate is converted into 4-hydroxyglutamate and (R)- 1-pyrroline-5-carboxylate is converted into D-glutamate. -!- NADP(+) can also act as acceptor, but with lower activity. -!- Formerly EC 1.5.1.12.
