This protein is involved in step 2 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 (hemL)
This subpathway is part of the pathway protoporphyrin-IX biosynthesis, which is itself part of Porphyrin-containing compound metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
