ENZYME entry: EC 7.1.3.1

Accepted Name
H(+)-exporting diphosphatase
Alternative Name(s)
H(+)-PPase
hydrogen-translocating pyrophosphatase
proton-pumping diphosphatase
proton-pumping pyrophosphatase
vacuolar H(+)-pyrophosphatase
Reaction catalysed
diphosphate + H(+)(in) + H2O = 2 H(+)(out) + 2 phosphate
Comment(s)
  • This enzyme, found in plants and fungi, couples the energy from diphosphate hydrolysis to active proton translocation across the tonoplast into the vacuole.
  • The enzyme acts cooperatively with cytosolic soluble diphosphatases to regulate the cytosolic diphosphate level.
