See more Tryptophan synthase or tryptophan synthetase is an enzyme (EC 4.2.1.20) that catalyses the final two steps in the biosynthesis of tryptophan. It is commonly found in Eubacteria, Archaebacteria, Protista See more α subunit reaction: The α subunit catalyzes the formation of indole and G3P from a retro-aldol cleavage of IGP. The αGlu49 and αAsp60 are thought to be directly involved in the catalysis as shown. The rate limiting step is the isomerization of IGP. See image 2. See more Tryptophan synthetase is also known to accept indole analogues, e.g., fluorinated or methylated indoles, as substrates, generating the corresponding tryptophan analogues. See more It is thought that early in evolution the trpB2 gene was duplicated. One copy entered the trp operon as trpB2i allowing for its expression with trpA. TrpB2i formed transient complexes with TrpA and in the process activated TrpA unidirectionally. The other copy … See more Subunits: Tryptophan synthase typically exists as an α-ββ-α complex.
