A simple method for determining kinetic constants of complexing inactivation at identical enzyme and inhibitor concentrations.
The kinetics of complexing inactivation at identical enzyme and inhibitor concentrations were analyzed and the equations of product generation were derived when the free enzyme concentration is great, larger or smaller than the dissociation constant of inhibitor, K(I). The kinetic constants can be obtained by fitting the derived equations to the progress curve. Numerical examples show that this method is valid and gives satisfactory results.
