CC   -!- FUNCTION: The alpha subunit is responsible for the aldol cleavage of
CC       indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate.
CC       {ECO:0000255|HAMAP-Rule:MF_00131}.
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         Evidence={ECO:0000255|HAMAP-Rule:MF_00131};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC       tryptophan from chorismate: step 5/5. {ECO:0000255|HAMAP-
CC       Rule:MF_00131}.
CC   -!- SUBUNIT: Tetramer of two alpha and two beta chains. {ECO:0000255|HAMAP-
CC       Rule:MF_00131}.
CC   -!- SIMILARITY: Belongs to the TrpA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00131}.
