Proteases are enzymes that hydrolyse peptide bonds between the residues that conform a protein. In every hydrolysis a water molecule is released. In every hydrolysis a water molecule is released. Specifically, a cysteine protease is an enzyme which breaks the peptide bond by using the thiol group of a cysteine residue as the nucleophile.
Actinidain (EC 3.4.22.14, actinidin, Actinidia anionic protease, proteinase A2 of Actinidia chinensis) is a type of cysteine protease enzyme found in fruits including kiwifruit (genus Actinidia), pineapple, mango, banana, figs, and papaya. This enzyme is part of the peptidase C1 family of papain-like proteases. [1] [2] [3] [4]

The enzyme is 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 a relatively heat-resistant enzyme, with an optimal temperature range of 60 to 70 °C. [9]

The first description of this enzyme was provided by Schack, [1] who named it papaya peptidase A. The same enzyme has since been given a number of different names, including papaya peptidase II, [4] papaya proteinase III [5] and papaya proteinase. [7] The name caricain was recommended by NC-IUBMB in 1992.
Protein shakes, made from protein powder (center) and milk (left), are a common bodybuilding supplement. Bodybuilders may supplement their diets with protein for reasons of convenience, lower cost (relative to meat and fish products), ease of preparation, and to avoid the concurrent consumption of carbohydrates and fats. Additionally, some ...
