Tryptophan synthase plant
WebApr 22, 2008 · In bacteria, such as Salmonella typhimurium, tryptophan is synthesized from indole-3-glycerole phosphate (IGP) by a tryptophan synthase αββα heterotetramer. Plants have evolved multiple α (TSA) and β (TSB) homologs, which have probably diverged in biological function and their ability of subunit interaction. There is some evidence for a … Web“With respect to the shikimate pathway, glyphosate targets this seven-step process by inhibiting a key enzyme known as EPSPS (5-enolpyruvylshikimate-3-phosphate synthase). When EPSPS is inhibited, the building of the amino acids necessary for the production of proteins is blocked and the plant dies.”

WebTRPS are bifunctional tetrameric enzymes that catalyzes the last two steps in the biosynthesis of l-tryptophan in bacteria, plants, and fungi, that is, the conversion of indole 3-glycerol phosphate and serine to tryptophan and water. 23–25,26–28 In bacteria, the two reactions are catalyzed by separate α and β-subunits, which combine to form a stable (αβ) …
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.
