Papain is a common enzyme obtained from the gre n papaya (Pawpaw) fruit. It is cysteine protease present in
Papaya, are es ential y synthesized as inactive proenzymes with N- terminal propeptide regions.The activation proces involves
removal of propeptide regions. Papain are used in many Industrial purposes, along with pharmaceuticals, fo d, leather, detergents and fish proces ing etc. The enzyme Papain was isolated from the unripe papaya fruit and obtained by milky latex
under suitable temperature and humidity. Papain was then manufactured by the proces involving the harvesting and drying of
latex. And, around 150 tonnes per year of Papain are produced in India. The study of Papain proteolytic action were done by the
method of hydrolysis of protein with the use of casein substrate and other method “ Absorptiometry”. Then the Papain was
purified by Gel filtration method with the use of sephadex G-75, Non denaturing Page method and SDS Page method, stained by
Co mas ie Blue R 250, and Bril iant blue G col oidal concentrated.
