1. An efficient nonenzymatic conversion of benzylpenicillin to 6-aminopenicillanic acid
2. One-step, high yield conversion of penicillin sulfoxides to deacetoxycephalosporins
3. Industrial transformations of penicillins and cephalosporins
4. Substrate specificity of immobilized penicillin-G acylase towards penicillin and cephalosporin derivatives was studied. The phenylacetyl moiety can be altered at the α-position with several small substituents. Depending on polarity and size of the substituent, enzyme activity decreases or increases. Insertion or deletion of atoms between the aromatic nucleus of the phenylacetyl group and the center of hydrolysis leads to substrates that are no longer recognized by the enzyme.
