This protein is involved in step 1 of the subpathway that synthesizes L-ornithine from N(2)-acetyl-L-ornithine (linear).
Proteins known to be involved in this subpathway in this organism are:
  1. Acetylornithine deacetylase (argE)
This subpathway is part of the pathway L-arginine biosynthesis, which is itself part of Amino-acid biosynthesis.
