Before revision:  The extended observation times for single proteoliposomes in solution allowed to observe fluctuating rotation rates of individual enzymes and to map the broad distributions of ATP-dependent calatytic rates in FoF1-ATP synthase .
After revision:  The extended observation times allowed us to observe fluctuating rotation rates of individual enzymes and to map the broad distributions of ATP-dependent calatytic rates in FoF1-ATP synthase .
