Graphical Abstract

Amphiphilic random copolymers were employed to construct enzyme nanoreactors for catalysis in an organic solvent. Unnatural selectivity over a range of substrates was introduced by tuning the cross-linking density.

Abstract

The utilization of enzymes for catalysis in organic solvents, while exhibiting selectivity to different substrates, is a big challenge. We report an amphiphilic random copolymer system that self-assembles with enzymes in an organic solvent to form nanoreactors. These encapsulated enzymes are not denatured and they do preserve the catalytic activity. The cross-linkable functional groups in the hydrophobic compartments of the polymers offer to control accessibility to the enzyme. This varied accessibility due to the polymer host, rather than the enzyme itself, endows the nanoreactor with an unnatural selectivity. The findings here highlight the significant potential of simple polymer-based enzyme nanoreactors to execute selective organic reactions under non-native conditions.
