Parallel approaches have been described for the preparation of polyacrylate-protease conjugates [396-400]. Acryloylation of subtilisin and a-chymotrypsin, followed by mixed polymerization with methyl methacrylate, vinyl acetate, styrene, or ethylvinyl ether, provides insoluble, doped polymethyl methacrylate, polyvinyl acetate, polystyrene, and polyethyl vinyl ether polymers [396]. These biocatalytic plastics perform especially well in hydrophilic and hydrophobic solvents, and have been used for peptide synthesis and the regioselective acylation of sugars and nucleosides. Similarly, modification of subtilisin and thermolysin with PEG monomethacrylate, then copolymerization with methyl methacrylate and trimethylolpropane trimethacrylate furnishes protease-polymethyl methacrylate plastics, which show good activities and stabilities in aqueous, mixed, and low-water and anhydrous organic media [397-400]. The protein-acrylate composites are unique in that they enable catalytic densities as high as 50% w/w.
