UniProtKB description: The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. In bacteria, tryptophan synthase alpha (TSA) activity is almost completely dependent on formation of an active alpha2beta2 complex with tryptophan synthase beta (TSB), and indole is usually not released during tryptophan synthesis. In maize, the TSA homolog BX1 catalyzes the formation of free indole from indole-3-glycerol phosphate, independently of TSB.
