Abstract
The substrate specificity of immobilized penicillin-Ci acylase towards penicillin and cephalosporin derivatives was studied. The phenylacety l moiety can be altered at the a-position with several small substitue nts. Depending on polarity and size of the substituent, enzyme activit y decreases or increases. Insertion or deletion of atoms between the a romatic nucleus of the phenylacetyl group and the center of hydrolysis leads to substrates that are no longer recognized by the enzyme.
