ENZYMATIC ENANTIOSELECTIVE ESTER OR AMIDE HYDROLYSIS OR SYNTHESIS

摘要

The enantioselectivity of fungal lipolytic enzymes can be altered by substituting a suitably selected amino acid residue. The residue to be substituted is selected from its location in the 3D structure of the enzyme and an ester substrate (or a substrate analogue). A residue in the lid may be selected if it is located close to the acid part or close to the alcohol part of an ester substrate. A residue outside the lid region may be selected if it is located close to the active site or close to the substrate.
