Abstract

Polyacrylamide beads (microgranules) containing covalently bound alpha-chymotrypsin were obtained. An average diameter of the microgranules is 100--150 micrometers. Prior to the bead polymerization alpha-chymotrypsin was modified by acryloyl chloride. The efficiency of the microgranulated alpha-chymotrypsin action depends on the kinetic properties of the substrates used. The pH optimum for the microgranulated enzyme activity towards N-acetyl-L-tyrosine ethyl ester is shifted by 1,5 units to the alkaline zone. The immobilized alpha-chymotrypsin is completely stable for 100 hrs at 50 degrees.
