== Function ==
[[http://www.uniprot.org/uniprot/TRPA_SALTY TRPA_SALTY]] The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. [[http://www.uniprot.org/uniprot/TRPB_SALTY TRPB_SALTY]] The beta subunit is responsible for the synthesis of L-tryptophan from indole and L-serine.
