Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA) By similarity. HAMAP-Rule MF_00087
Catalytic activity	L-glutamate 1-semialdehyde + NADP+ + tRNA(Glu) = L-glutamyl-tRNA(Glu) + NADPH. HAMAP-Rule MF_00087
Pathway	Porphyrin-containing compound metabolism; protoporphyrin-IX biosynthesis; 5-aminolevulinate from L-glutamyl-tRNA(Glu): step 1/2. HAMAP-Rule MF_00087
Subunit structure	Homodimer By similarity. HAMAP-Rule MF_00087
Domain	Possesses an unusual extended V-shaped dimeric structure with each monomer consisting of three distinct domains arranged along a curved 'spinal' alpha-helix. The N-terminal catalytic domain specifically recognizes the glutamate moiety of the substrate. The second domain is the NADPH-binding domain, and the third C-terminal domain is responsible for dimerization By similarity. HAMAP-Rule MF_00087
Miscellaneous	During catalysis, the active site Cys acts as a nucleophile attacking the alpha-carbonyl group of tRNA-bound glutamate with the formation of a thioester intermediate between enzyme and glutamate, and the concomitant release of tRNA(Glu). The thioester intermediate is finally reduced by direct hydride transfer from NADPH, to form the product GSA By similarity.
Sequence similarities	Belongs to the glutamyl-tRNA reductase family.
