CC   -!- FUNCTION: The alpha subunit is responsible for the aldol cleavage
CC       of indoleglycerol phosphate to indole and glyceraldehyde 3-
CC       phosphate.
CC   -!- CATALYTIC ACTIVITY: L-serine + 1-C-(indol-3-yl)glycerol 3-
CC       phosphate = L-tryptophan + D-glyceraldehyde 3-phosphate + H(2)O.
CC       {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.
CC   -!- INTERACTION:
CC       P0A2K1:trpB; NbExp=22; IntAct=EBI-1028423, EBI-1028431;
CC   -!- SIMILARITY: Belongs to the TrpA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00131}.
