Soybean lipoxygenase (EC 22.214.171.124) incorporated into the reversed micelles of aerosol OT in octane has been studied for its catalytic properties. The enzyme is shown to preserve up to 10% activity as compared with the activity in the aqueous solution. In this case Km of lipoxygenase for linoleic acid increases from 10(-5) M to 5 X 10(-4) M. The activity of lipoxygenase is maximal, the aerosol OT concentration being 0.03 M and a degree of reversed micelle hydratation 40. Cationic detergents of the cetyltrimethyl ammonium bromide type are not good to form reversed micelles of lipoxygenase, since they inhibit the latter with IC50 = (4 divided by 6) x 10(-4) M. The lipoxygenase preparations in reversed micelles of aerosol OT in octane may be used to synthesize natural metabolites of polyunsaturated fatty acids, for instance of eicosanoids.
