V-ATPase are mainly found in vacuoles of eukaryotic cells where they catalyze the hydrolyzation of [[ATP]] in order to transport solutes.

The structure of the whole V-ATPase complex can be divided in two domains. The V1 domain, which consist of eight different sub-units (A-H) and is responsible for the hydrolyzation of ATP, and the intermembrane V0 domain consisting of six different sub-units (a-f) and which transports the protons.
