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.
