CC -!- FUNCTION: Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu)
CC to glutamate 1-semialdehyde (GSA). {ECO:0000256|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;
CC Evidence={ECO:0000256|ARBA:ARBA00001415, ECO:0000256|HAMAP-
CC Rule:MF_00087, ECO:0000256|RuleBase:RU000584};
CC -!- PATHWAY: Porphyrin-containing compound metabolism; protoporphyrin-IX
CC biosynthesis; 5-aminolevulinate from L-glutamyl-tRNA(Glu): step 1/2.
CC {ECO:0000256|ARBA:ARBA00005059, ECO:0000256|HAMAP-Rule:MF_00087,
CC ECO:0000256|RuleBase:RU000584}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|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:0000256|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:0000256|HAMAP-Rule:MF_00087}.
CC -!- SIMILARITY: Belongs to the glutamyl-tRNA reductase family.
CC {ECO:0000256|ARBA:ARBA00005916, ECO:0000256|HAMAP-Rule:MF_00087,
CC ECO:0000256|RuleBase:RU000584}.
