General annotation (Comments)

Function

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. HAMAP-Rule MF_00134_B

Catalytic activity

N-(5-phospho-beta-D-ribosyl)anthranilate = 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate. HAMAP-Rule MF_00134_B

1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate = 1-C-(3-indolyl)-glycerol 3-phosphate + CO2 + H2O. HAMAP-Rule MF_00134_B

Pathway

Amino-acid biosynthesis; L-tryptophan biosynthesis; L-tryptophan from chorismate: step 3/5. HAMAP-Rule MF_00134_B

Amino-acid biosynthesis; L-tryptophan biosynthesis; L-tryptophan from chorismate: step 4/5.

Subunit structure

Monomer.

Sequence similarities

In the N-terminal section; belongs to the TrpC family.

In the C-terminal section; belongs to the TrpF family.
