Abstract
Disclosed is an ionic liquid-coated enzyme, wherein the ionic liquid is an organic salt which presents as a liquid phase at a temperature of about 150° C. or below. The ionic liquid-coated enzyme according to the present invention remarkably improves enzyme functions, such as enantioselectivity and stability, when the enzyme which may be lipase is coated with an ionic liquid. Further, even in the case of when the ionic liquid-coated enzyme is reused, the enantiomeric excess, enantioselectivity, and activity are not degenerated. The coated enzyme is usable as a catalyst for providing a chiral intermediate required in the synthesis of chiral pesticides, medicines, natural chemicals, and so on.
