Description

EnkiLife provides the Recombinant E.coli Trp B (N-6His) protein,aslo know as Tryptophan synthase beta chain,trpB, which features high purity, high activity, and high stability. It can be applied in scientific research, biopharmaceuticals, and other fields.Purity:Greater than 95% as determined by reducing SDS-PAGE;Endotoxin Level:<1 EU/µg as determined by LAL test.;Construction:Recombinant E.coli Tryptophan Synthase Beta Chain is produced by our E.coli expression system and the target gene encoding Thr2-Ile397 is expressed with a 6His tag at the N-terminus.Accession:P0A879. Expression Host:E.coli.Species:E.coli.Predicted Molecular Mass:43.8 KDa. Background:Tryptophan synthase is an enzyme that catalyzes the final two steps in the biosynthesis of tryptophan. It is commonly found in Eubacteria, Archaebacteria, Protista, Fungi, and Plantae, but is absent from animals such as humans. Tryptophan synthase typically exists as an α-ββ-α complex.The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate: L-serine + 1-C-(indol-3-yl)glycerol 3-phosphate = L-tryptophan + D-glyceraldehyde 3-phosphate + H2O.The beta subunits catalyze the irreversible condensation of indole and serine to form tryptophan in a pyridoxal phosphate (PLP) dependent reaction. Their assembly into a complex leads to structural changes in both subunits resulting in reciprocal activation.
