ATPase is an enzyme which catalyzes the breakdown of ATP into ADP and a phosphate ion. This dephosphorylation releases energy which the enzyme uses to drive other reactions[1]. The F1/0 ATPase is called ATP synthase synthesises the reverse reaction, i.e., the addition of phosphate to ADP to form ATP[2]. ATPase types include:

  • F-ATPase - the prime producers of ATP[3]. For details see Alice Clark/ATPsynthase;
  • V-ATPase or Vacuolar-type H+ ATPase couples the energy to proton transport across membranes. For details see V-ATPase;
  • A-ATPase are found in archaea. For details see A-ATP Synthase;
  • P-ATPase transport ions[4]
  • E-ATPase hydrolyze extracellular ATP[5].
  • MipZ is an ATPase which forms a complex with the chromosome partitioning protein ParB and is responsible for the regulation of FtsZ ring formation.

ATPase domains include metal-binding domain (MBD) and nucleotide-binding domain (NBD). For more details see:
