Multifunctional tryptophan biosynthesis protein

Gene

TRP1

Organism
Cryptococcus neoformans var. neoformans serotype D (strain B-3501A) (Filobasidiella neoformans)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Trifunctional enzyme bearing the Gln amidotransferase (GATase) domain of anthranilate synthase, indole-glycerolphosphate synthase, and phosphoribosylanthranilate isomerase activities.

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.
Chorismate + L-glutamine = anthranilate + pyruvate + L-glutamate.

Pathwayi: L-tryptophan biosynthesis

This protein is involved in step 1, 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. Multifunctional tryptophan biosynthesis protein (TRP1)
  2. no protein annotated in this organism
  3. Multifunctional tryptophan biosynthesis protein (TRP1)
  4. Multifunctional tryptophan biosynthesis protein (TRP1)
  5. Tryptophan synthase (CNBA6100)
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.
