Protein attributes

Sequence length	1224 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Oxidizes proline to glutamate for use as a carbon and nitrogen source, and also functions as a transcriptional repressor of its own gene.
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.
