    • It is intended to provide an assay method whereby the activity of a lipid-modifying enzyme can be conveniently measured over a wide range and a drug capable of controlling a lipid-modifying enzyme with the use of this assay method. The above problem can be solved by, for example, a method of measuring the activity of a lipid-modifying enzyme which comprises the steps of (I) preparing a lipid micelle containing a biotinylated lipid and a substrate for the lipid-modifying enzyme; (II) bringing the lipid micelle prepared in the above step (I) into contact with the lipid-modifying enzyme; and (III) evaluating the activity of the lipid-modifying enzyme by applying an evaluation method using the proximity effect to the product obtained in the above step (II).
    • 旨在提供一种测定方法,其中可以在宽范围内方便地测量脂质修饰酶的活性,并且使用能够使用该测定方法控制脂质修饰酶的药物。 上述问题可以通过例如测定脂质修饰酶的活性的方法来解决,该方法包括以下步骤:(I)制备含有生物素化脂质和脂质修饰酶底物的脂质胶束; (II)使上述步骤(I)中制备的脂质胶束与脂质修饰酶接触; 和(III)通过使用对上述步骤(II)中获得的产物的邻近效应的评价方法评估脂质修饰酶的活性。
