  7. Histidinol-phosphate aminotransferase (hisC)
  8. no protein annotated in this organism
  9. Histidinol dehydrogenase (hisD)
This subpathway is part of the pathway L-histidine biosynthesis, which is itself part of Amino-acid biosynthesis.

Pathway:iL-tryptophan biosynthesis

This protein is involved in step 3 of the subpathway that synthesizes L-tryptophan from chorismate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Anthranilate synthase component 1 (trpE)
  2. Anthranilate phosphoribosyltransferase (trpD)
  3. Phosphoribosyl isomerase A (priA)
  4. Indole-3-glycerol phosphate synthase (trpC)
  5. Tryptophan synthase beta chain (trpB), Tryptophan synthase alpha chain (trpA)
