ATPase

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. The F1/0 ATPase is called ATP synthase synthesises the reverse reaction, i.e., the addition of phosphate to ADP to form ATP. ATPase types include:

• F-ATPase - the prime producers of ATP. 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;
  
• E-ATPase hydrolyze extracellular ATP.
  
• 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:
