Effect of deep eutectic solvents on activity, stability, and selectivity of enzymes: Novel insights and further prospects.

Deep eutectic solvents (DESs) have been extensively concerned since 2008 as reaction media in biocatalysis because of their excellent solvent performances. Here, we try to clarify the effects of DESs on the catalytic properties, structure, and conformation of enzymes. Through comprehensive analysis, it is found that the catalytic properties of enzymes can be designed in different DESs through modulating the hydrogen bond acceptors, hydrogen bond donors, and their molar ratio.
