Herein, we report the synthesis of enzyme-polymer conjugates. Four different activated polymers are conjugated to the surface of protease, α-amylase and lipase using two different strategies. The covalent attachment of polymers increased the thermal stability and the stability in a standard detergent formulation compared to the unmodified enzymes. The enzyme-polymer conjugates are characterized by asymmetrical-flow-field-flow fractionation and differential scanning microcalorimetry. Furthermore, we demonstrate that conjugated enzymes still show performance in a real washing process. In our opinion, enzyme-polymer conjugates show a potential as a stabilizing system for enzymes in detergents.
