  • Additionally, this drug group includes protease or proteolytic enzymes but also includes many others. (mindzymes.com)
  • These results show that biosensor-based interaction studies can resolve affinity into association and dissociation rates, and that these are characteristic parameters for the interaction between enzymes and inhibitors. (beactica.com)
