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.
CC {ECO:0000256|ARBA:ARBA00025592}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1-(2-carboxyphenylamino)-1-deoxy-D-ribulose 5-phosphate + H(+)
CC = (1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate + CO2 + H2O;
