CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=chorismate + L-glutamine = anthranilate + H(+) + L-glutamate +
CC         pyruvate; Xref=Rhea:RHEA:21732, ChEBI:CHEBI:15361, ChEBI:CHEBI:15378,

CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=diphosphate + N-(5-phospho-beta-D-ribosyl)anthranilate = 5-
CC         phospho-alpha-D-ribose 1-diphosphate + anthranilate;

CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:58017; EC=2.4.2.18;
CC   -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC       tryptophan from chorismate: step 1/5.
CC   -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC       tryptophan from chorismate: step 2/5.
CC   -!- SUBUNIT: Tetramer of two components I and two components II.
CC   -!- MISCELLANEOUS: Component I catalyzes the formation of anthranilate
CC       using ammonia rather than glutamine, whereas component II provides
CC       glutamine amidotransferase activity.
CC   -!- MISCELLANEOUS: In E.coli and certain other bacteria, component II is
CC       larger and its C-terminal two thirds has anthranilate
CC       phosphoribosyltransferase activity.
