General description

The mechanism by which it breaks peptide bonds involves deprotonation of Cys-25 by His-159. Asparagine-175 helps to orient the imidazole ring of His-159 to allow this deprotonation to take place. Cys-25 then performs a nucleophilic attack on the carbonyl carbon of a peptide backbone. This frees the amino terminal of the peptide, and forms a covalent acyl-enzyme intermediate. The enzyme is then deacylated by a water molecule, and releases the carboxy terminal portion of the peptide. In immunology, papain is known to cleave the Fc (crystallisable) portion of immunoglobulins (antibodies) from the Fab (antigen-binding) portion.Papain is relatively heat resistant enzyme

Function and Application 

1 Its utility is in breaking down tough meat fibers

2 dissociate cells in the first step of cell culture preparations

3 Papain can also be found as an ingredient in some toothpastes or mints as teeth-whitener.

4 it is the main ingredient of Papacarie
