CC -!- FUNCTION: The alpha subunit is responsible for the aldol cleavage
CC of indoleglycerol phosphate to indole and glyceraldehyde 3-
CC phosphate (By similarity).
CC -!- CATALYTIC ACTIVITY: L-serine + 1-C-(indol-3-yl)glycerol 3-
CC phosphate = L-tryptophan + glyceraldehyde 3-phosphate + H(2)O.
CC -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC tryptophan from chorismate: step 5/5.
CC -!- SUBUNIT: Tetramer of two alpha and two beta chains (By
CC similarity).
CC -!- SIMILARITY: Belongs to the TrpA family.
