Protein attributes

Sequence length	420 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the NADPH dependent reduction of L-gamma-glutamyl 5-phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate. HAMAP MF_00412
Catalytic activity	L-glutamate 5-semialdehyde + phosphate + NADP+ = L-glutamyl 5-phosphate + NADPH. HAMAP MF_00412
Pathway	Amino-acid biosynthesis; L-proline biosynthesis; L-glutamate 5-semialdehyde from L-glutamate: step 2/2. HAMAP MF_00412
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the gamma-glutamyl phosphate reductase family.
