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}.
