| Research Abstract |
The proton (H+) pumping vacuolar-type ATPase (V-ATPase) is a rotary enzyme comprising multiple subunits that plays a pivotal role in forming intracellular acidic compartments in eukaryotic cells. We have recorded the rotation speed of the V-ATPase using a single molecule analysis system for the first time. We have also identified a temperature-sensitive amino acid motif that is conserved in mammalian V-ATPase E subunits.
