Pathwayi: protoporphyrin-IX biosynthesis

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.
