FunFam 1: Glutamyl-tRNA reductase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Glutamyl-tRNA reductase. [EC: 1.2.1.70]
L-glutamate 1-semialdehyde + NADP(+) + tRNA(Glu) = L-glutamyl-tRNA(Glu) + NADPH.
  • Forms part of the pathway for the biosynthesis of 5-aminolevulinate from glutamate, known as the C5 pathway, which is used in most eubacteria, and in all archaebacteria, algae and plants.
  • However, in the alpha-proteobacteria EC 2.3.1.37 is used in an alternative route to produce the product 5-aminolevulinate from succinyl-CoA and glycine.
  • This route is found in the mitochondria of fungi and animals, organelles that are considered to be derived from an endosymbiotic alpha-proteobacterium.
  • Although higher plants do not possess EC 2.3.1.37, the protistan Euglena gracilis possesses both the C5 pathway and EC 2.3.1.37.
