How proteolysis regulate enzymatic activity?

Proteolysis regulates enzymatic activity by selectively cleaving precursor proteins or enzymes, activating or inactivating them through the removal of specific peptide segments. This post-translational modification can lead to conformational changes that enhance or inhibit the enzyme's catalytic function. Additionally, proteolytic cleavage can serve as a mechanism for turning off enzyme activity once it is no longer needed, allowing for precise control of metabolic pathways. Thus, proteolysis is crucial for maintaining homeostasis in biological systems.
