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 Xref=Rhea:RHEA:10532, ChEBI:CHEBI:15377, ChEBI:CHEBI:33384,
