Description
| - Haloalkane dehalogenases are microbial enzymes with a wide range of biotechnological applications. The use of organic co-solvents to solubilize their hydrophobic substrates is often necessary. In order to choose the most compatible co-solvent, the effects of fourteen co-solvents on activity, stability and enantioselectivity of three model enzymes, DbjA, DhaA and LinB, were evaluated. All co-solvents caused at high concentration loss of activity and conformational changes. The highest inactivation was induced by tetrahydrofuran, while more hydrophilic co-solvents, such as ethylene glycol and dimethyl sulfoxide, were more tolerated. The effects of co-solvents at low concentration were different for each enzyme-solvent pair. The increase in DbjA activity was induced by the majority of organic co-solvents tested, while activities of DhaA and LinB decreased at comparable concentrations of the same co-solvent. Moreover, high increase of DbjA enantioselectivity was observed.
