[reaction--see text] Penicillin G acylase (penicillin amidohydrolase, E.C. 3.5.1.11) was immobilized in a simple and effective way by physical aggregation of the enzyme, using a precipitant, followed by chemical cross-linking to form insoluble cross-linked enzyme aggregates (CLEAs). These had the same activity in the synthesis of ampicillin as cross-linked crystals of the same enzyme, but the accompanying
