ATP synthase, also called Complex V, has two distinct components: F1, a peripheral membrane protein, and Fo (o denoting oligomycin-sensitive), which is integral to the membrane. F1, was identified and purified by Efraim Racker and his colleagues in the early 1960s.

ATP, a major currency of energy, is synthesized by ATP synthase. This enzyme is composed of a membrane-embedded, proton-conducting portion, F0, and a 

ATP synthase is composed of two linked multi-subunit complexes: the soluble catalytic core, F 1, and the membrane-spanning component, F o, comprising the proton channel. The catalytic portion of mitochondrial ATP synthase consists of 5 different subunits (alpha, beta, gamma, delta, and epsilon) assembled with a stoichiometry of 3 alpha, 3 beta, and a single representative of the other 3. The F1 portion of the ATP synthase is above the membrane, inside the matrix of the mitochondria. Mitochondria structure: (1) inner membrane, (2) outer membrane, (3) cristae, (4) matrix The nomenclature of the enzyme suffers from a long history.

F 1, a water-soluble ATPase portion of F oF 1, rotates by repeating ATP-waiting dwell, 80° substep rotation, catalytic dwell, and 40°-substep rotation. Compared with F 1, rotation of F oF 1 has yet been The 12 identical subunits that compose the Fo portion of ATP synthase are designated. gamma.

The F0 portion of ATP synthase allows these ions to flow back, turning the rotor in the process. As the rotor turns, it turns the axle and the F1 motor becomes a generator, creating ATP as it turns. Remarkably, cells build similar molecular machines, such as the vacuolar ATPase , that work in reverse, using an ATP-driven motor to pump protons across a membrane.

The F 1 F O-ATP synthase is the only enzyme in nature endowed with bi-functional catalytic mechanism of synthesis and hydrolysis of ATP.The enzyme complex is hosted in the inner mitochondrial membrane in eukaryotes and in the plasma-membrane in bacteria. Under aerobic conditions this enzyme complex has the main task of building the molecule of ATP, the energy currency of the cell. 2015-10-13 ATP synthase is composed of two linked multi-subunit complexes: the soluble catalytic core, F1, and the membrane-spanning component, Fo, comprising the proton channel. The catalytic portion of mitochondrial ATP synthase consists of 5 different subunits (alpha, beta, gamma, delta, and epsilon) assembled with a stoichiometry of 3 alpha, 3 beta, and a single representative of the other 3.

ATP synthase manufactures ATP from two smaller chemicals, ADP and phosphate. ATP synthase (or F1F0 ATPase) is the central enzyme in biological energy conversion, synthesizing ATP from ADP and inorganic phosphate using the free energy derived from protonmotive force.

File:ATPsynthase labelled.png. Structure of ATP synthase, the F 0 proton channel and rotating stalk are shown in blue, the F 1 synthase domain in red and the membrane in grey.. An ATP synthase (EC 3.6.3.14) is a general term for an enzyme that can synthesize adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate by using some form of energy.

The role of ATP synthase in the F1 sector is to synthesize ATP from ADP and inorganic phosphate (Pi). This is made possible by a gradient of protons crossing the inner mitochondrial membrane that is from the intermembrane space and enter the matrix through the Fo portion of the enzyme. The c subunit is an inner mitochondrial membrane (IMM) protein encoded by three nuclear genes. Best known as an integral part of the F 0 complex of the ATP synthase, the c subunit is also present in other cytoplasmic compartments in ceroid lipofuscinoses.
