Descripción general
Papain is a cysteine protease of the papain family. It is a single chain protein. The molecular weight of papain is 23 kDa. Papain is composed of two structural domains and a cleft between them, which consists of the active site.
Aplicación
Papain has been used in the digestion of various brain cells.
Use Papain for the complete proteolytic cleavage of proteins, limited hydrolysis of native immunoglobulins, and tissue dissociation (together with collagenase, esterase, and trypsin). The enzyme solubilizes integral membrane proteins and produces glycopeptides from purified proteoglycans. The addition of cysteine (approximately 0.5% [w/v]) is essential for enzyme activity.
Acciones bioquímicas o fisiológicas
Papain exhibits proteolytic activity against amide links, amino acid esters, peptides, proteins. It mainly cleaves peptide bonds containing amino acids such as lysine, arginine and residues succeeding phenylalanine. It can catalyze several reactions, such as hydrolysis, transferase action, specificity and acyl-enzyme intermediate.
