Papain Immobilization Study in Enzymatic Synthesis of Dipeptide Gly-Phe

Papain catalysed peptide synthesis was followed to determine the optimum conditions for adsorption and covalent binding immobilization methods. The synthesis of the dipeptide Gly-Phe was studied in two different reaction systems: a) For adsorbed papain, in an organic medium containing low water concentration, b) For covalently bound enzyme, in a two-liquid phase system, using trichloroethylene as organic phase. The amount of enzyme offered to the immobilization support and the pH of the immobilization procedure were the main parameters studied.
