Resumen

α-Chymotrypsin was immobilized in activated agarose support and the stability of the biocatalyst was assessed in three polar organic solvents, namely, ethanol, diglyme, and acetonitrile. Ethanol was the solvent in which the stability of the enzyme was higher and was then selected to perform the synthesis of the kyotorphin derivative benzoyl-tyrosine argininamide, evaluating enzyme reactivation after synthesis. Substrates for reaction were benzoyl tyrosine ethyl ester and argininamide, the reaction being performed under kinetic control. High conversion yield (85%) was obtained and the immobilized enzyme was successfully used in sequential batch reactor operation with enzyme reactivation after three batches.
