Examples
Although many gelatin desserts incorporate fruit, some fresh fruits contain proteolytic enzymes ; these enzymes cut the gelatin molecule into peptides (protein fragments) too small to form a firm gel.
Amyloytic enzymes such as amylase aid in the breakdown of starch in the grains to sugar and dextrin, citation while proteolytic enzymes such as protease catalyze the breakdown of proteins into smaller peptides or amino acids.
A good example is the blood clotting cascade whereby an initial event triggers a cascade of sequential proteolytic activation of many specific proteases, resulting in blood coagulation.
Cysteine residues play a valuable role by crosslinking proteins, which increases the rigidity of proteins and also functions to confer proteolytic resistance (since protein export is a costly process, minimizing its necessity is advantageous).
Effector caspases are then activated by these active initiator caspases through proteolytic cleavage.
Biological functions Post-translational proteolytic processing Limited proteolysis of a polypeptide during or after translation in protein synthesis often occurs for many proteins.
