May 1987; Journal of Biological Chemistry 262 The ATP synthase Although the Fo portion of the ATP synthase is often referred to as "proton(ic) channel", it is NOT a channel. It differs significantly from "real" proton channels (e.g. gramicidin, M2 from influenza virus, etc.).

F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a is a paracrystalline protein thin layer attached to the outermost portion

The streaming of protons through the Fo “pore” causes the cylinder of c subunits and the attached γ subunit to rotate about the long axis of γ, which is perpendicular to the plane of the membrane. FoF1-ATP synthase (FoF1) is a motor enzyme that couples ATP synthesis/hydrolysis with a transmembrane proton translocation. F1, a water-soluble ATPase portion of FoF1, rotates by repeating ATP-waiting dwell, 80° substep rotation, catalytic dwell, and 40°-substep rotation.

The FO region of ATP synthase is a proton pore that is embedded in the mitochondrial membrane. It consists of three main subunits A, B, and C, and (in humans) six additional subunits, d, e, f, g, F6, and 8 (or A6L). E. coli ATP synthase is the simplest known form of ATP synthase, with 8 different subunit types. The ATP synthase is associated with the cytoplasmic membrane and consists of two parts: the peripheral F1 portion and the integral F0 complex. The F1 portion carries the catalytic centers of the enzyme (for review see Ref. 1). Fo portion of Escherichia coli ATP synthase: orientation of subunit c in the membrane Eukaryote membrane genetics: the Fo sector of mitochondrial ATP synthase F o F 1-ATP synthase is one of the most ubiquitous enzymes; it is found widely in the biological world, including the plasma membrane of bacteria, inner membrane of mitochondria and thylakoid membrane of chloroplasts.

F1, was identified and purified by Efraim Racker and his colleagues in the early 1960s. The FO region of ATP synthase is a proton pore that is embedded in the mitochondrial membrane.

Proton translocation across the FO region that spans the mitochondrial inner membrane drives ATP synthesis in the F1 region through a rotational mechanism. Guo et al. present a high-resolution structure of the dimeric FO complex from Saccharomyces cerevisiae 2008-01-01 · We review recent advances in understanding of the structure of the F 1 F 0 ‐ATP synthase of the mitochondrial inner membrane (mtATPase). A significant achievement has been the determination of the structure of the principal peripheral or stator stalk components bringing us closer to achieving the Holy Grail of a complete 3D structure for the complex.

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 function of ATP synthase.
