Ion-combination specific effects driving the enzymatic activity of halophilic alcohol dehydrogenase 2 from in aqueous ionic liquid solvent mixtures.

Biocatalysis in ionic liquids enables novel routes for bioprocessing. Enzymes derived from extremophiles promise greater stability and activity under ionic liquid (IL) influence. Here, we probe the enzyme alcohol dehydrogenase 2 from the halophilic archaeon in thirteen different ion combinations for relative activity and analyse the results against molecular dynamics (MD) simulations of the same IL systems.
