Alkaline treatment of corn can release tryptophan. There are two general ways of controlling enzyme activity: Controls enzyme levels; Control of catalytic activity The number of enzymes in a cell depends on the rate of synthesis and degradation of a product. 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… fitting bath panels
