Cysteine protease inhibitors are available that can block the active site but no such inhibitor available yet that can be targeted to block the pro-mature domain interactions and prevent it activation. The pro-mature domain interaction can be categorized as protein– protein interactions (PPIs) and may be targeted in a range of diseases. For activation of the mature enzyme, removal of the prodomain is necessary and achieved by different modes. The prodomain acts as an endogenous inhibitor of the mature enzyme. For preventing unwanted digestion, cysteine proteases are synthesized as zymogens, and contain a prodomain (regulatory) and a mature domain (catalytic).

Therefore, they are promising drug targets for various diseases. This review will cover only cysteine proteases, papain family enzymes which are involved in multiple functions such as extracellular matrix turnover, antigen presentation, processing events, digestion, immune invasion, hemoglobin hydrolysis, parasite invasion, parasite egress, and processing surface proteins.

Proteases are classified according to their catalytic site, and distributed into four major classes: cysteine proteases, serine proteases, aspartic proteases, and metalloproteases. Proteases cleave proteins into smaller fragments by catalyzing peptide bonds hydrolysis.

No.Proteolytic enzymes are crucial for a variety of biological processes in organisms ranging from lower (virus, bacteria, and parasite) to the higher organisms (mammals).
