The vacuolar ATPase integral membrane c-ring from Nephrops norvegicus occurs in paired complexes in a double membrane. Using cryo-electron microscopy and single particle image processing of 2D crystals, we have obtained a projection structure of the c-ring of N. norvegicus. The c-ring was found to be very flexible, most likely as a result of an expanded conformation of the c subunits. This structure may support a role for the vacuolar ATPase c-rings in membrane fusion.
