CC   -!- FUNCTION: Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu)
CC       to glutamate 1-semialdehyde (GSA). {ECO:0000255|HAMAP-Rule:MF_00087}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(S)-4-amino-5-oxopentanoate + NADP(+) + tRNA(Glu) = H(+) + L-
CC         glutamyl-tRNA(Glu) + NADPH; Xref=Rhea:RHEA:12344, Rhea:RHEA-
CC         COMP:9663, Rhea:RHEA-COMP:9680, ChEBI:CHEBI:15378, ChEBI:CHEBI:57501,
CC         ChEBI:CHEBI:57783, ChEBI:CHEBI:58349, ChEBI:CHEBI:78442,
CC         ChEBI:CHEBI:78520; EC=1.2.1.70; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00087};
CC   -!- PATHWAY: Porphyrin-containing compound metabolism; protoporphyrin-IX
CC       biosynthesis; 5-aminolevulinate from L-glutamyl-tRNA(Glu): step 1/2.
CC       {ECO:0000255|HAMAP-Rule:MF_00087}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00087}.
CC   -!- DOMAIN: Possesses an unusual extended V-shaped dimeric structure with
CC       each monomer consisting of three distinct domains arranged along a
CC       curved 'spinal' alpha-helix. The N-terminal catalytic domain
CC       specifically recognizes the glutamate moiety of the substrate. The
CC       second domain is the NADPH-binding domain, and the third C-terminal
CC       domain is responsible for dimerization. {ECO:0000255|HAMAP-
CC       Rule:MF_00087}.
CC   -!- MISCELLANEOUS: During catalysis, the active site Cys acts as a
CC       nucleophile attacking the alpha-carbonyl group of tRNA-bound glutamate
CC       with the formation of a thioester intermediate between enzyme and
CC       glutamate, and the concomitant release of tRNA(Glu). The thioester
CC       intermediate is finally reduced by direct hydride transfer from NADPH,
CC       to form the product GSA. {ECO:0000255|HAMAP-Rule:MF_00087}.
CC   -!- SIMILARITY: Belongs to the glutamyl-tRNA reductase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00087}.
