ATP synthase delta/epsilon subunit is a part of the ATP synthase and the F-ATPase family in general. It is known as the delta subunit in mitochondrial ATP syntheses, and the epsilon subunit in bacterial and chloroplastic ATP syntheses. It is part of the rotor between subunits F1 and FO. [1] Its C terminal domain seems to inhibit ATPase activity of the synthase. [2]

ATP synthase class of enzymes

ATP synthase is an enzyme that creates the energy storage molecule adenosine triphosphate (ATP). ATP is the most commonly used "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:

MT-ATP8 A mitochondrial protein-coding gene whose product is involved in ATP synthesis

MT-ATP8 is a mitochondrial gene with the full name 'mitochondrially encoded ATP synthase membrane subunit 8' that encodes a subunit of mitochondrial ATP synthase, ATP synthase Fo subunit 8. This subunit belongs to the Fo complex of the large, transmembrane F-type ATP synthase. This enzyme, which is also known as complex V, is responsible for the final step of oxidative phosphorylation in the electron transport chain. Specifically, one segment of ATP synthase allows positively charged ions, called protons, to flow across a specialized membrane inside mitochondria. Another segment of the enzyme uses the energy created by this proton flow to convert a molecule called adenosine diphosphate (ADP) to ATP. Subunit 8 differs in sequence between Metazoa, plants and Fungi.
