membrane-bound Fo complex of F-ATP synthase, subunit c; Subunit c (also called subunit 9, or proteolipid) of the Fo complex of F-ATP synthase. The F-ATP synthase (also called FoF1-ATPase) consists of two structural domains: the F1 (factor one) complex containing the soluble catalytic core, and the Fo (oligomycin sensitive factor) complex containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. F1 is composed of alpha, beta, gamma, delta, and epsilon subunits with a stoichiometry of 3:3:1:1:1, while Fo consists of the three subunits a, b, and c (1:2:10-14). An oligomeric ring of 10-14 c subunits (c-ring) make up the Fo rotor. The flux of protons though the ATPase channel (Fo) drives the rotation of the c-ring, which in turn is coupled to the rotation of the F1 complex gamma subunit rotor due to the permanent binding between the gamma and epsilon subunits of F1 and the c-ring of Fo. The F-ATP synthases are primarily found in the inner membranes of eukaryotic mitochondria, in the thylakoid membranes of chloroplasts, or in the plasma membranes of bacteria. The F-ATP synthases are the primary producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts). Alternatively, under conditions of low driving force, ATP synthases function as ATPases, thus generating a transmembrane proton or Na(+) gradient at the expense of energy derived from ATP hydrolysis. This group also includes F-ATP synthase that has also been found in the archaea Methanosarcina acetivorans.

ATP synthase, membrane-bound Fo/Vo/Ao complexes, subunit c; Subunit c of the Fo/Vo/Ao complex is the main transmembrane subunit of F-, V- or A-type family of ATP synthases with rotary motors. These ion-transporting rotary ATP synthases are composed of two linked multi-subunit complexes: the F1, V1, and A1 complexes contains three copies each of the alpha and beta subunits that form the soluble catalytic core, which is involved in ATP synthesis/hydrolysis, and the Fo, Vo, or Ao (oligomycin sensitive) complex that forms the membrane-embedded proton pore. The F-ATP synthases (also called FoF1-ATPases) are found in the inner membranes of eukaryotic mitochondria, in the thylakoid membranes of chloroplasts, or in the plasma membranes of bacteria. F-ATPases are the primary producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts). Alternatively, under conditions of low driving force, ATP synthases function as ATPases, thus generating a transmembrane proton or Na(+) gradient at the expense of energy derived from ATP hydrolysis. The A-ATP synthase (AoA1-ATPases) is exclusively found in archaea and function like F-ATP synthase. Structurally, however, the A-ATP synthase is more closely related to the V-ATP synthase (vacuolar VoV1-ATPase), which is a proton-translocating ATPase responsible for acidification of eukaryotic intracellular compartments and for ATP synthesis in archaea and some eubacteria. Collectively, F-, V-, and A-type synthases can function in both ATP synthesis and hydrolysis modes.

ATP synthase, F0 subunit c; This model describes the subunit c in F1/F0-ATP synthase, a membrane associated multisubunit complex found in bacteria and organelles of higher eukaryotes, namely, mitochondria and chloroplast. This enzyme is principally involved in the synthesis of ATP from ADP and inorganic phosphate by coupling the energy derived from the proton electrochemical gradient across the biological membrane. A brief description of this multisubunit enzyme complex: F1 and F0 represent two major clusters of subunits. The functional role of subunit c, which is the part of F0 cluster, has been delineated in-vitro reconstitution experiments. Overall experimental proof exists that demonstrate the electrochemical gradient is converted into a rotational torque that leads to ATP synthesis.

Membrane-bound Vo/Ao complexes of V/A-type ATP synthases, subunit c; Vo/Ao-ATP synthase subunit c. The V- and A-type family of ATPases are composed of two linked multi-subunit complexes: the V1 and A1 complexes contain three copies each of the alpha and beta subunits that form the soluble catalytic core, which is involved in ATP synthesis/hydrolysis, and the Vo or Ao complex that forms the membrane-embedded proton pore. The A-ATP synthase (AoA1-ATPases) is exclusively found in archaea and functions like the F-ATP synthase.

The V- and A-type synthases can function in both ATP synthesis and hydrolysis modes. The V1 complex consists of three A and three B subunits, two G subunits plus the C, D, E, F, and H subunits. The Vo complex consists of five different subunits: a, c, c', c'', and d. The Ao/A1 complexes are composed of nine subunits in a stoichiometry of A(3):B(3):C:D:E:F:H(2):a:c(x). ATP is synthesized on the A3:B3 hexamer and the energy released during that process is transferred to the Ao complex, which consists of the C-terminal segment of subunit a and subunit c.
