Biological functions Post-translational proteolytic processing Limited proteolysis of a polypeptide during or after translation in protein synthesis often occurs for many proteins.
Cleavage of polyproteins Some proteins and most eukaryotic polypeptide hormones are synthesized as a large precursor polypeptide known as a polyprotein that requires proteolytic cleavage into individual smaller polypeptide chains.
