    6.2.1.4 | denaturing of the enzyme in 6 M guanidinium chloride for 24 h and refolding by rapid dilution (1:20 v:v) into one of three solutions: benign buffer consisting of 50 mM KCl, 60 mM potassium phosphate pH 7.4, arginine buffer containing 0.67 M L-arginine-HCl, 60 mM potassium phosphate, pH 7.4, or arginine buffer containing 0.67 M L-arginine-HCl, 60 mM potassium phosphate, 50 mM Tris-HCl, pH 8.0, kinetics of refolding, overview. Enzyme refolding in arginine buffer, pH 7.4, is temperature-dependent, the rate of refolding follows apparent first-order kinetics. Omission of phosphate from the buffer does not affect the rate. The refolded enzyme form is much less thermostable than the native form |
