[Immobilization of enzymes on globulin]

Immobilization of lipase and amylosubtilisin on water-insoluble proteins, i. e. globulins, was studied. It was found that immobilization results in the enzyme stabilization. The immobilized enzyme can be transformed from the soluble state into the insoluble one and vice versa by changing the ionic strength of the solution. The advantages of immobilization on globulin in the reactions with water-insoluble substrates are demonstrated.
