RT "The distribution, diversity and function of predominant Thermoproteales in
RT high-temperature environments of Yellowstone National Park.";
RL Submitted (DEC-2015) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: The alpha subunit is responsible for the aldol cleavage of
CC indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate.
CC {ECO:0000256|ARBA:ARBA00003365}.
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:0000256|ARBA:ARBA00000003};
CC -!- PATHWAY: Amino-acid biosynthesis; L-tryptophan biosynthesis; L-
CC tryptophan from chorismate: step 5/5. {ECO:0000256|ARBA:ARBA00004733}.
CC -!- SUBUNIT: Tetramer of two alpha and two beta chains.
CC {ECO:0000256|ARBA:ARBA00011270}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KUO85130.1}.
