Kinetic Measurements to Investigate the Oxygen-Sensing

The activity of cysteine proteases is regulated by a few general mechanisms, which includes the production of zymogens, selective expression, pH modification, cellular compartmentalization, and regulation of their enzymatic activity by endogenous inhibitors, which seemingly is the most efficient mechanism associated with the regulation of the activity of cysteine proteases. Proteases are usually synthesized as large precursor proteins called zymogens, such as the seri… WebCathepsins have specific pH levels at which they have optimum proteolytic activity.
