WebNov 26, 2024 · Tryptophan 2,3-dioxygenase (TDO, formerly known as tryptophan pyrrolase) is a cytosolic hemoprotein that plays a rate-limiting role in tryptophan degradation . When inhibited in the liver, plasma tryptophan build-up occurs, with augmented tryptophan brain uptake [ 101 ] and, reasonably, enhanced serotonin (5-HT) and 5-hydroxyindoleacetic acid … 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, Fungi, and Plantae. However, it is absent from Animalia. It is typically found as an α2β2 tetramer. The α subunits … See more 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 … See more Tryptophan synthase is commonly found in Eubacteria, Archaebacteria, Protista, Fungi, and Plantae.
