Kinetics and mechanism of hydrolysis of acetylthiocholine by butyrylcholine esterase.
Kinetics and mechanism of hydrolysis of acetylthiocholine by the enzyme butyrylcholine esterase was studied. The spectrophotometric Ellman's method and potentiometric pH-stat method were used for continuous determination of the actual concentration of the products thiocholine and acetic acid in the reaction mixture. The validity of the Michaelis-Menten (Briggs-Haldane) equation in the whole cou...
متن کاملKINETIC STUDY OF THE pH INFLUENCE ON BSA THERMAL DENATURATION
BSA solution and the buffer used as a solvent, A is the area of the V = f(T) plot obtained for a given step of the considered thermal denaturation process and a is the part of this surface corresponding to a given temperature T. In this study some conformational changes induced by thermal denaturation of BSA macromolecule were evidenced, the temperatures of transition as well as the # G values ...
متن کاملInfluence of a Novel Magnetic Recoverable Support on Kinetic, Stability and Activity of Beta-amylase Enzyme
In this paper, covalent immobilization of beta amylase enzyme on the surface of modified magnetic nano particles (ZnFe2O4@SiO2-NH2) is reported. For doing so, at first, the magnetic nanoparticles of ZnFe2O4 were synthesized by chemical co-precipitation method and then tetraethyl orthosilicate (TEOS) and 3-aminopropyltriethoxy sil...
