Tryptophan Synthase

Tryptophan synthase is an enzyme that catalyzes the final two steps in the biosynthesis of tryptophan. It is commonly found in Eubacteria, Archaebacteria, Protista, Fungi, and Plantae. However, it is absent from Animalia. [1]

Tryptophan synthase is a classic enzyme that channels a metabolic intermediate, indole
