In enzymology, a trypanothione synthase (EC 6.3.1.9) is an enzyme that catalyzes the chemical reaction glutathione + glutathionylspermidine + ATP $${\displaystyle \rightleftharpoons }$$ N1,N8-bis(glutathionyl)spermidine + ADP + phosphateThe 3 substrates of this enzyme are glutathione, glutathionylspermidine, … See more The active bifunctional enzyme of trypanothione synthase is found as a 74.4 KDa monomer consisting of 652 residues with two catalytic domains. Its C-terminal domain is a synthetase and has an ATP-grasp family fold … See more The main function of trypanothione synthase is to use the free energy generated from ATP hydrolysis to conjugate glutathione and spermidine to form the intermediate of glutathionylspermidine and then the final product of … See more The regulation of trypanothione synthase is currently thought to be driven by conformational changes caused by allosteric … See more The current believed mechanism for synthetase activity is that first glutathione and Mg -ATP bind to the enzyme in a ternary complex where glutathione becomes activated by ATP and forms glutathionyl phosphate. ADP then leaves the active site and … See more Many diseases such as Human African trypanosomiasis, Nagana disease in cattle, and Chagas disease are caused by kinetoplastid … See more WebJan 1, 2024 · Trypanothione synthetase (TryS) is a trypanosomatid-specific enzyme that catalyzes the two-step synthesis of trypanothione (T(SH) 2; N 1,N 8-bis(glutathionyl)spermidine), from two molecules of glutathione (GSH; L-γ-Glu-Cys-Gly) and a spermidine core along with ATP consumption . shangri la flowers
