Organism
Helicobacter pylori (strain ATCC 700392 / 26695) (Campylobacter pylori)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Bifunctional enzyme that catalyzes two sequential steps of tryptophan biosynthetic pathway. The first reaction is catalyzed by the isomerase, coded by the TrpF domain; the second reaction is catalyzed by the synthase, coded by the TrpC domain (By similarity).By similarity

Catalytic activityi

N-(5-phospho-beta-D-ribosyl)anthranilate = 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate.
1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate = 1-C-(3-indolyl)-glycerol 3-phosphate + CO2 + H2O.

Pathway: L-tryptophan biosynthesis

This protein is involved in step 3 and 4 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 2 (trpG), Anthranilate synthase component 1 (trpE)
  2. Anthranilate phosphoribosyltransferase (trpD)
  3. Tryptophan biosynthesis protein TrpCF (trpC)
  4. Uncharacterized protein (HP_0276), Tryptophan biosynthesis protein TrpCF (trpC)
  5. Tryptophan synthase beta chain (trpB), Tryptophan synthase alpha chain (trpA)
This subpathway is part of the pathway L-tryptophan biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-tryptophan from chorismate, the pathway L-tryptophan biosynthesis and in Amino-acid biosynthesis.
