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}.
