H+, Na+-translocating pyrophosphatase family

Members of the H+, Na+-translocating Pyrophosphatase (M+-PPase) Family (TC# 3.A.10) are found in the vacuolar (tonoplast) membranes of higher plants, algae, and protozoa, and in both bacteria and archaea. They are therefore ancient enzymes. Two distinct biochemical subclasses of H+-PPases have been characterised to date: K+-stimulated and K+-insensitive.
