Details:	"The V-ATPase-an engine for transport and traffic" ABSTRACT Compartmentation allows the simultaneous occurrence of biochemical processes in different reaction spaces and necessitates the exchange of material via membrane transport or vesicular intermediates. In my presentation, I will focus on the V-ATPase, a proton pump found throughout the endomembrane system of all eukaryotes and will demonstrate that it is not only important for secondary active membrane transport but also for membrane trafficking. Specifically, I will discuss the importance of the Arabidopsis V-ATPase for the dynamics and identity of the trans-Golgi network/early endosome as well as the contribution of the V-ATPase at the tonoplast to vacuolar acidification and transport.
