| Abstract: | Regulation of the membrane active properties of alkaline phosphatase from calf intestinal mucosa in reversed micelles of Aerosol OT (AOT) in octane was studied. The dependence of the catalytic activity on the surfactant concentration at the constant hydration degree, which characterises the membrane activity of enzymes, is modulated through pH variation. The variation may cause conformational changes of the protein molecule, resulting in exposition of anchor groups which provide the interaction of the enzyme with the micellar matrix. |
