WebFeb 1, 2024 · Continuous access to nutrients is a primary requirement for cell proliferation, and controlling nutrient supply is an ancient survival strategy that may additionally regulate immune response. Indoleaine 2,3-dioxygenase (IDO) is a tryptophan enzyme composed of two-helical α-domains with a heme group located between them (1–2). 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…
