| Abstract: | This work presents a kinetic study on irreversible inhibition of trypsin by TLCK, using a new experimental approach. The method consists of the incubation of the enzyme with an irreversible inhibitor in the presence of a substrate which allows enzyme turnover as well as continuous measurement of the appearance of the product, a simultaneous change in the initial concentrations of the irreversible inhibitor and enzyme being undertaken, though a constant ratio between the latter, is maintained. This new approach enables the kinetic constants for TLCK, k2 and K1, to be determined. |
