SUBSTRATE-FIXED PENICILLIN G AMIDASE, GLUTARYL-7-ACA ACYLASE OR D-AMINOACID OXIDASE

摘要

The invention concerns an enzyme, selected from the group comprising penicillin G amidase (E.C. 3.5.1.11), glutaryl-7-ACA acylase and d-aminoacid oxidase (E.C. 1.4.3.3), which is fixed by covalent bonding to a substrate made of an amino-substituted organosiloxane polymer. The invention also concerns a method of improving the activity per unit volume of enzymes fixed in this way.
