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.
