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