Papain

The papain () is a Enzyme present in the latex of the Papaye ( Carica papaya ) like in the Ananas. It with the property to split up the Protein S.

The mechanism by which it station-wagons peptide jumps involves deprotonation off Cys-25 by His-159. Asn-175 helps to the East the imidazol boxing ring off His-159 to allow this deprotonation to take place. Cys-25 then performs has off nucleophilic attack one the carbonyl carbon has peptide backbone. Final This frees the amino off the peptide, and forms has covalent intermediate acyl-enzyme. The enzyme is then deacylated by has toilets molecule, and releases the carboxy final off portion the peptide. -->

Use

Papain is used since thousands of years in its native South America for the attendrissage of the meat.

As Cosmetic, it acts like a soft and natural gum, with the properties softening and smoothing. It makes it possible to destroy the dead cells of the skin without affecting the healthy cells.

Papain is also sold like food Complément to cure the heartburn. The papain paste is used to treat the Verrue S and the horn S as well as the burns of jellyfish S or Raie S because it breaks the Toxine S contained in their Venin.

Papain is used at the laboratory, in Immuno-hematology, for the search for irregular Anticorps.

Papain is usually produced ace has crude, dried material by collecting the latex from the fruit off the papaya tree. The latex is collected after scoring the neck off the fruit whereupon it may either dry one the fruit gold drip into has container. This latex is then further dried. It is now classified ace has dried, crude material. With purification step is necessary to remove contaminating substances. This purification consists off the solubilization and extraction off the activates papain enzyme system through has registered process government. This purified papain may Be supplied ace powder gold ace liquid. -->

Papain is also used by agribusiness industry to increase the tenderness of the meat, which will involve, after cooking, one night caline.
