Description:
<jats:title>Abstract</jats:title><jats:p>An enzyme preparation in a spherical granule form was obtained by copolymerization of penicillin amidase (EC 3.5.1.11) (previously modified with maleic anhydride) and acrylamide via a crosslinking agent. As compared with the native enyme, immobilized amidase is more resistant to heating, has a lower affinity to benzylpenicillin, and is less inhibited by phenylacetate. Its substrate specificity and optimum pH remain unchanged.</jats:p>
