CC -!- FUNCTION: Housekeeping enzyme that catalyzes the last step in proline
CC biosynthesis. In some cell types, such as erythrocytes, its primary
CC function may be the generation of NADP(+). Can utilize both NAD and
CC NADP. Has higher affinity for NADP, but higher catalytic efficiency
CC with NADH (By similarity). Involved in cellular response to oxidative
CC stress (By similarity). {ECO:0000250|UniProtKB:Q96C36}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-proline + NADP(+) = 1-pyrroline-5-carboxylate + 2 H(+) +
CC NADPH; Xref=Rhea:RHEA:14109, ChEBI:CHEBI:15378, ChEBI:CHEBI:15893,
CC ChEBI:CHEBI:57783, ChEBI:CHEBI:58349, ChEBI:CHEBI:60039; EC=1.5.1.2;

CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:60039; EC=1.5.1.2;
CC Evidence={ECO:0000250|UniProtKB:Q96C36};
CC -!- PATHWAY: Amino-acid biosynthesis; L-proline biosynthesis; L-proline
CC from L-glutamate 5-semialdehyde: step 1/1.
CC -!- SUBUNIT: Homodecamer; composed of 5 homodimers. Interacts with LTO1.
CC {ECO:0000250|UniProtKB:Q96C36}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q96C36}.
CC Mitochondrion {ECO:0000250|UniProtKB:Q96C36}.
CC -!- SIMILARITY: Belongs to the pyrroline-5-carboxylate reductase family.
CC {ECO:0000305}.
