CC   -!- FUNCTION: Bifunctional enzyme that catalyzes two sequential steps of
CC       tryptophan biosynthetic pathway. The first reaction is catalyzed by the
CC       isomerase, coded by the TrpF domain; the second reaction is catalyzed
CC       by the synthase, coded by the TrpC domain (By similarity).
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=N-(5-phospho-beta-D-ribosyl)anthranilate = 1-(2-
CC         carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate;
