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.
