Before revision:  In this work electrode-immobilized glucose-6-phosphate dehydrogenase enzyme catalyzed a reaction which carries out the Boolean AND logic gate. We report the first experimental realization of a sigmoid shape response in one of the gate inputswhich is a desirable shape for biocomputing application as it allows reduction of the analog noise .
After revision:  In this work we survey filtering in general, in biochemical computing, and summarize the experimental realization of a sigmoid shape response in one of the gate inputswhich is a desirable shape for biocomputing application as it allows reduction of the analog noise .
