Protein

Glutamyl-tRNA reductase

Gene

hemA

Organism
Bacillus clausii (strain KSM-K16)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA).UniRule annotation

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.UniRule annotation

Catalytic activityi

L-glutamate 1-semialdehyde + NADP+ + tRNA(Glu) = L-glutamyl-tRNA(Glu) + NADPH.UniRule annotation

Pathwayi: protoporphyrin-IX biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes 5-aminolevulinate from L-glutamyl-tRNA(Glu).UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Glutamyl-tRNA reductase (hemA)
  2. Glutamate-1-semialdehyde 2,1-aminomutase 1 (hemL1), Glutamate-1-semialdehyde 2,1-aminomutase 2 (hemL2)
This subpathway is part of the pathway protoporphyrin-IX biosynthesis, which is itself part of Porphyrin-containing compound metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 5-aminolevulinate from L-glutamyl-tRNA(Glu), the pathway protoporphyrin-IX biosynthesis and in Porphyrin-containing compound metabolism.

Domaini

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.UniRule annotation

Sequence similaritiesi

Belongs to the glutamyl-tRNA reductase family.UniRule annotation
