Papain - Wikipedia
Papain, also known as papaya proteinase I, is a cysteine protease (EC 3.4.22.2) enzyme present in papaya (Carica papaya) and mountain papaya (Vasconcellea cundinamarcensis). It is the namesake member of the papain-like protease family.
The Structure of Papain - ScienceDirect
1971年1月1日 · The chapter discusses the enzymatic properties of papain. Papain can catalyze a number of reaction—namely, acyl-enzyme intermediate, hydrolysis, transferase action, and specificity. X-ray diffraction can provide a wealth of information on a protein structure. The papain molecule consists of one folded polypeptide chain of 212 residues.

Papain is a sulfhydryl protease from the latex of the papaya fruit. Its molecules consist of one polypeptide chain with 212 amino acid residues. The chain is folded into two domains with the active site in a groove between the domains.
Papain - Proteopedia, life in 3D
Papain is a relatively simple enzyme, consisting of a single 212 residue chain. A majority of papain's residues are as shown in fuchsia. As with all proteins, it is primarily the exclusion of these residues by water that leads to papain's assumption of a globular form.
Papain - PubChem
Papain, also known as papaya proteinase I, is a cysteine protease (EC 3.4.22.2) enzyme that is found in species of papaya, Carica papaya and Vasconcellea cundinamarcensis. The enzyme is found to be localized in the skin of papaya, and is collected from slashed unripe papayas as …
Papain - an overview | ScienceDirect Topics
Papain, a proteolytic enzyme, is obtained from Carica papaya fruits. It possesses a wide variety of nutritional, medical, and pharmaceutical applications. Papain primarily breaks peptide bonds present in basic amino acids, especially arginine, lysine, and phenylalanine.
Papain (EC 3.4.22.2) is an endolytic plant cysteine protease enzyme which is isolated from papaya ( Carica papaya L.) latex. Papain is obtained by cutting the skin of the unripe papaya and then collecting and drying the latex which flows from the cut. The greener the fruit, more active is the papain. Papain enzyme belongs to the
