Enzyme kinetics is the study of the chemical reactions that are catalyzed by enzymes. In enzyme kinetics, technicians measure reaction rates and investigate the effects of the varying conditions of the reaction. Studying an enzyme's kinetics can reveal the catalytic mechanism of this enzyme, its role in metabolism, how its activity is controlled, and how a drug or an agonist might inhibit the enzyme.
We use different analytical techniques in order to capture the changes in the concentration of the substrate or product over a defined period of time. Optical methods, especially UV-Vis spectrophotometry, are particularly well suited for this task. Here, the absorbance is measured at a defined wavelength - either continuously or at a defined point in time. The advantage of continuous measurement is that the entire process can be monitored. In this way, the behavior of the assay can be monitored for deviations, and the linear range is easily defined. The enzyme activity can then be calculated based on the change in absorbance per unit time.
For the measurement process, we determine the appropriate environmental parameters (e.g. temperature and pH). Their consistency throughout the experiment should be guaranteed, as they can severely affect enzyme activity. Parameters to be defined include the measurement wavelength, temperature and measurement duration and, if applicable, the defined measurement interval. Accurate pipetting and careful mixing are essential. In addition, care must be taken to start measurements immediately after the addition of the final reagent.
