RL   Submitted (DEC-2006) to the EMBL/GenBank/DDBJ databases.
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}.
