Protein attributes

Sequence length	1312 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (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 By similarity.
Catalytic activity	L-proline + acceptor = (S)-1-pyrroline-5-carboxylate + reduced acceptor. (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. Amino-acid degradation; L-proline degradation into L-glutamate; L-glutamate from L-proline: step 2/2.
Sequence similarities	In the N-terminal section; belongs to the proline dehydrogenase family. In the C-terminal section; belongs to the aldehyde dehydrogenase family.
