CC -!- FUNCTION: The beta subunit is responsible for the synthesis of L-
CC tryptophan from indole and L-serine. {ECO:0000256|ARBA:ARBA00002786,
CC ECO:0000256|HAMAP-Rule:MF_00133}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate + L-serine = D-
CC glyceraldehyde 3-phosphate + H2O + L-tryptophan;
CC Xref=Rhea:RHEA:10532, ChEBI:CHEBI:15377, ChEBI:CHEBI:33384,
