ATP synthase is an enzyme that creates the adenosine triphosphate (ATP) energy storage molecule. ATP is the most common "energy currency" of cells for all organisms. It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi). The overall reaction catalyzed by ATP synthase is:
ADP + Pi + 3H + out ⇌ ATP + H2O + 3H + in
The formation of ATP from ADP and P i is energetically unfavorable and will usually go the other way. To push this reaction forward, ATP synthase pairs ATP synthesis during cell respiration to the electrochemical gradient created by the difference in proton (H +) concentration across the mitochondrial plasma membrane in eukaryotes or plasma membranes in bacteria.
ATP synthase consists of two main subunits, FO and F 1, which have a motor rotation mechanism that allows for the production of ATP. Because of its rotating subunits, ATP synthase is a molecular machine.
the main function of ATP synthase in most organisms is the synthesis of ATP. Therefore named as such. However, in some cases the reaction can be the opposite, that is, the pumping of a transmembrane proton activated by ATP hydrolysis is more important. An example: anaerobic bacteria produce ATP by fermentation, and ATP synthase uses ATP to produce the driving force of protons needed for ion transport and motility of flagella.
