Papain, is one kind of proteolytic enzyme, can hydrolyze antibody molecules into three segments. It is one kind low specificity proteolytic enzymes, active center contain homocysteine, belongs to thiol protease.
Cas No.: 9001-73-4
Other name: papayotin, Papaya enzyme
Papain belongs to thiol protease, it has a a wide substrate specificity, act on L-arginine,
L-lysine and L-Citrulline in the protein.
Papain is one kind of protease which can break down protein in all acidity, neutral and alkaline environment. It’s appearance is white to light yellow powder, having tiny hygroscopicity.
Papain protease (papain), also called Papaya Enzyme. Its extraction source is the milk in the fruits of immature Carica papaya, by adopting advanced modern biological engineering technology, it is refined to pure natural enzyme products.
It is a kind of enzymes containing –SH peptide chain, it has the activity of Protease and Esterase, which has a wide range of specificity. It has strong hydrolysis ability to plant and animal protein, polypeptide, ester, amide and etc. Meanwhile, it also has compositing functionalities, can synthesis Lactalbumin Hydrolysate to proteinoid. Soluble in water and glycerin, aqueous solution is colorless or light yellow, sometimes oyster white, hardly soluble in alcohol, chloroform, diethyl ether and so on such organic solvents.
