Beschreibung
Zusammenfassung:Provided herein are systems and components thereof for improving protease activity. The systems make use of an emulsion for in vitro compartmentalization of a library of synthetic compounds, each compound having a gene linked to a protease substrate and selectable marker. Expressed enzymes with greater protease activity will preferentially hydrolyze the protease substrate, whereas enzymes with less protease activity will leave the substrate intact. Removal of the non-hydrolyzed compounds provides an enriched gene library encoding for more active protease variants. Also described are synthetic compounds and emulsions which can be used in the methods.
