Subunits: Tryptophan synthase typically exists as an α-ββ-α complex. The α and β subunits have molecular masses of 27 and 43 kDa respectively. The α subunit has a TIM barrel conformation. The β subunit has a fold type II conformation and a binding site adjacent to the active site for monovalent cations. Their assembly into a complex leads to structural changes in both subunits resulting in reciprocal activation. There are two main mechanisms for intersubunit communicati… WebNov 9, 2015 · Tryptophan synthase (TrpS; EC 4.2.1.20) is a heterodimeric complex that catalyzes the formation of l-tryptophan (Trp, 1) from l-serine (Ser, 2) and indole glycerol phosphate (IGP, 3; Fig. 1A) ().The mechanism of this transformation has been extensively studied for TrpS from Escherichia coli and Salmonella typhimurium, where it has been …
