In MacroFun, the efforts are focussed on establishing structural and mechanistic know-how to better understand the interface between enzymes and macromolecules, to develop enzymes for the functionalisation of polymer surfaces and the directed and specific assembly, conversion and degradation of biopolymers. Thereby, an improvement of enzymatic processes and novel applications for a selective degradation, activation and functionalisation of natural and synthetic polymers will be developed. New enzyme systems for efficient biotransformation of polymers and the assembly of  bioresponsive devices will be established
