Comments

FUNCTION: Oxidizes proline to glutamate for use as a carbon and nitrogen source and also function as a transcriptional repressor of the put operon.
CATALYTIC ACTIVITY: L-proline + acceptor = (S)-1-pyrroline-5-carboxylate + reduced acceptor.
CATALYTIC ACTIVITY: (S)-1-pyrroline-5-carboxylate + NAD(P)⁺ + 2 H₂O = L-glutamate + NAD(P)H.
COFACTOR: FAD.
PATHWAY: Amino-acid degradation; L-proline degradation into L-glutamate; L-glutamate from L-proline: step 1/2 .
PATHWAY: Amino-acid degradation; L-proline degradation into L-glutamate; L-glutamate from L-proline: step 2/2 .
INDUCTION: By proline, autorepression and catabolite repression, and is potentially nitrogen controlled.
