Figure 1. Organisation of V-ATPase and its glucose-dependent dissociation.

Figure 1

V-ATPase is composed of a peripheral sector V1 (green), which carries the ATPase activity, and the proton-conducting, membrane-integral V0 sector (red and yellow). Only the V1 and V0 sector subunits used in this work are indicated. The black star in the V0 a-subunit Vph1 represents the residue R735. Glucose withdrawal releases V1 from V0 and renders it soluble in the cytosol. Proton conductance by V0 is blocked in this state.
