This enzyme catalyses the irreversible oxidation of glutamate-¦Ã-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, proline dehydrogenase) is in spontaneous equilibrium with its tautomer L-glutamate ¦Ã-semialdehyde. In many bacterial species, both activities are carried out by a single bifunctional enzyme [3,4].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 [5]. |
