Proteolysis is the hydrolysis of peptide bonds, which leads to proteins breaking down into shorter peptide chains or into their amino acid constituents. Protein hydrolysis is usually catalysed by enzymes called proteostases, but can also occur due to chemicals such as certain types of venom.

Proteolysis can serve a variety of biological functions, including protein digestion, apoptosis, regulating cell cycle, cellular homeostasis and preventing accumulation of aggregated or misfolded proteins.[1]
