CC   -!- FUNCTION: Bifunctional enzyme that catalyzes two sequential steps
CC       of tryptophan biosynthetic pathway. The first reaction is
CC       catalyzed by the isomerase, coded by the trpF domain; the second
CC       reaction is catalyzed by the synthase, coded by the trpC domain.
CC   -!- CATALYTIC ACTIVITY: N-(5-phospho-beta-D-ribosyl)anthranilate = 1-
CC       (2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate.
CC   -!- CATALYTIC ACTIVITY: 1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-
CC       phosphate = 1-C-(3-indolyl)-glycerol 3-phosphate + CO(2) + H(2)O.
CC   -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC       tryptophan from chorismate: step 3/5.
CC   -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC       tryptophan from chorismate: step 4/5.
CC   -!- SIMILARITY: In the N-terminal section; belongs to the trpC family.
CC   -!- SIMILARITY: In the C-terminal section; belongs to the trpF family.
