CC -!- FUNCTION: Catalyzes the NADPH-dependent reduction of L-glutamate 5-
CC phosphate into L-glutamate 5-semialdehyde and phosphate. The product
CC spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate.
CC {ECO:0000255|HAMAP-Rule:MF_00412}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-glutamate 5-semialdehyde + NADP(+) + phosphate = H(+) + L-
CC glutamyl 5-phosphate + NADPH; Xref=Rhea:RHEA:19541,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:43474, ChEBI:CHEBI:57783,
CC ChEBI:CHEBI:58066, ChEBI:CHEBI:58274, ChEBI:CHEBI:58349; EC=1.2.1.41;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00412};
CC -!- PATHWAY: Amino-acid biosynthesis; L-proline biosynthesis; L-glutamate
CC 5-semialdehyde from L-glutamate: step 2/2. {ECO:0000255|HAMAP-
CC Rule:MF_00412}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00412}.
CC -!- SIMILARITY: Belongs to the gamma-glutamyl phosphate reductase family.
CC {ECO:0000255|HAMAP-Rule:MF_00412}.
