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;
CC Xref=Rhea:RHEA:21540, ChEBI:CHEBI:18277, ChEBI:CHEBI:58613;
CC EC=5.3.1.24;
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;
CC Xref=Rhea:RHEA:23476, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16526, ChEBI:CHEBI:58613, ChEBI:CHEBI:58866; EC=4.1.1.48;
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 -!- SUBUNIT: Monomer. {ECO:0000250}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the TrpC family.
CC {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the TrpF family.
CC {ECO:0000305}.
