Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core, and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Part of the complex F(1) domain and of the central stalk which is part of the complex rotary element. Rotation of the central stalk against the surrounding alpha(3)beta(3) subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits.

The F-ATPase is found in bacterial plasma membranes, mitochondrial inner membranes, and in chloroplast thylakoid membranes. It uses a proton gradient to drive ATP synthesis and hydrolyzes ATP to build the proton gradient. The extrinsic membrane domain, F1, is composed of alpha, beta, gamma, delta, and epsilon subunits (only found in eukaryotes, lacking in bacteria) with a stoichiometry of 3:3:1:1:1. Alpha and beta subunit form the globular catalytic moiety, a hexameric ring of alternating subunits. Gamma, delta and epsilon subunits form a stalk, connecting F1 to F0, the integral membrane proton translocating domain.The epsilon subunit is thought to be involved in the regulation of ATP synthase, since a null mutation increased oligomycin sensitivity and decreased inhibition by inhibitor protein IF1. Length = 45

This family constitutes the mitochondrial ATP synthase epsilon subunit. This is not to be confused with the bacterial epsilon subunit, which is homologous to the mitochondrial delta subunit (pfam00401 and pfam02823) The epsilon subunit is located in the extrinsic membrane section F1, which is the catalytic site of ATP synthesis. The epsilon subunit was not well ordered in the crystal structure of bovine F1, but it is known to be located in the stalk region of F1. E subunit is thought to be involved in the regulation of ATP synthase, since a null mutation increased oligomycin sensitivity and decreased inhibition by inhibitor protein IF1. Length = 49

ATPases can harness the energy from a proton gradient, using the flux of ions across the membrane via the ATPase proton channel to drive the synthesis of ATP. Some ATPases work in reverse, using the energy from the hydrolysis of ATP to create a proton gradient. There are different types of ATPases, which can differ in function (ATP synthesis and/or hydrolysis), structure (e.g., F-, V- and A-ATPases, which contain rotary motors) and in the type of ions they transport [, ]. The different types include: F-ATPases (F1F0-ATPases), which are found in mitochondria, chloroplasts and bacterial plasma membranes where they are the prime producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts). V-ATPases (V1V0-ATPases), which are primarily found in eukaryotic vacuoles and catalyse ATP hydrolysis to transport solutes and lower pH in organelles. A-ATPases (A1A0-ATPases), which are found in Archaea and function like F-ATPases (though with respect to their structure and some inhibitor responses, A-ATPases are more closely related to the V-ATPases). P-ATPases (E1E2-ATPases), which are found in bacteria and in eukaryotic plasma membranes and organelles, and function to transport a variety of different ions across membranes. E-ATPases, which are cell-surface enzymes that hydrolyse a range of NTPs, including extracellular ATP. F-ATPases (also known as F1F0-ATPase, or H(+)-transporting two-sector ATPase) (3.6.3.14 from EC) are composed of two linked complexes: the F1 ATPase complex is the catalytic core and is composed of 5 subunits (alpha, beta, gamma, delta, epsilon), while the F0 ATPase complex is the membrane-embedded proton channel that is composed of at least 3 subunits (A-C), nine in mitochondria (A-G, F6, F8). Both the F1 and F0 complexes are rotary motors that are coupled back-to-back. In the F1 complex, the central gamma subunit forms the rotor inside the cylinder made of the alpha(3)beta(3) subunits, while in the F0 complex, the ring-shaped C subunits forms the rotor. The two rotors rotate in opposite directions, but the F0 rotor is usually stronger, using the force from the proton gradient to push the F1 rotor in reverse in order to drive ATP synthesis []. These ATPases can also work in reverse to hydrolyse ATP to create a proton gradient. This family constitutes the mitochondrial ATP synthase epsilon subunit, which is distinct from the bacterial epsilon subunit (the latter being homologous to the mitochondrial delta subunit, IPR001469 from INTERPRO). The mitochondrial epsilon subunit is located in the stalk region of the F1 complex, and acts as an inhibitor of the ATPase catalytic core. The epsilon subunit can assume two conformations, contracted and extended, where the latter inhibits ATP hydrolysis. The conformation of the epsilon subunit is determined by the direction of rotation of the gamma subunit, and possibly by the presence of ADP. The extended epsilon subunit is thought to become extended in the presence of ADP, thereby acting as a safety lock to prevent wasteful ATP hydrolysis [].
