CC -!- FUNCTION: The beta subunit is responsible for the synthesis of L-
CC tryptophan from indole and L-serine. {ECO:0000255|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,
CC ChEBI:CHEBI:57912, ChEBI:CHEBI:58866, ChEBI:CHEBI:59776; EC=4.2.1.20;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00133};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00133};
CC -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC tryptophan from chorismate: step 5/5. {ECO:0000255|HAMAP-
CC Rule:MF_00133}.
CC -!- SUBUNIT: Tetramer of two alpha and two beta chains. {ECO:0000255|HAMAP-
CC Rule:MF_00133}.
CC -!- SIMILARITY: Belongs to the TrpB family. {ECO:0000255|HAMAP-
CC Rule:MF_00133}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAQ60430.1; Type=Erroneous initiation; Evidence={ECO:0000305};
