ATP Synthase is a complex structure consisting of two domains F o and F 1. F 1 is a spherical structure, which, in the case of mitochondria, sticks out into the matrix and is anchored to the membrane by a stator to prevent rotation. The F 1 F o ATP synthases in eukaryotes (mitochondria, thylakoids of chloroplasts) and eubacteria (but not archaea) are from sequence analyses very similar, and so a universal proton to H + /ATP was expected. ATP synthase and the complexes that form the electron transport chain (ETC) are located throughout the cisternae. ATP is synthesized by a machine that may be even more remarkable, the ATP synthase (also called F-ATPase or FoF1-ATPase). As shown in the figure, the ATP synthase is an intricate rotary machine consisting of ∼ 20 proteins. ATP synthase is a ubiquitous membrane enzyme that plays a key role in biological energy metabolism.

ATP synthase is made of two structural subunits called F1 and F0. These ATP synthases are found in mitochondria, chloroplasts, and bacteria. The F1 complex is spherical in shape and attached on the mitochondria inner membrane with the help of stalk. ATP Synthase: A Molecular Motor. ATP synthase is a huge molecular complex (>500,000 daltons) embedded in the inner membrane of mitochondria.Its function is to convert the energy of protons (H +) moving down their concentration gradient into the synthesis of ATP. 3 to 4 protons moving through this machine is enough to convert a molecule of ADP and P i (inorganic phosphate) into a molecule of ATP. L'ATP synthase appartient au groupe EC 7 des translocases.

All ATP-synthase complexes producing great amounts of ATP in living organisms are coupled to chains of electron transporters integrated in membranes or in lipid–protein lamellar structures, which are named transducing membranes. Chloroplast ATP synthase and the enzyme from some photosynthetic bacteria have 2 different, although similar, b-type subunits in the proton translocating F O p ortion, namely b and b', one copy of each. High homology is found for most of the ATP synthase subunits from different bacteria and chloroplasts. 2001-09-01 · ATP synthase is a ubiquitous, highly conserved enzyme that catalyses the formation of ATP from ADP and P i using a unique rotary motor mechanism..

ATP is synthesized by ATP synthase, a large complex of membrane-bound protein. Here we see ATP synthase, along with other membrane-bound proteins. Notice the large difference in the number of hydrogen ions on the two sides of the membrane. Die ATP-Synthase lässt sich funktionell in eine bewegbliche Einheit, der Rotor, und eine starre Einheit, der Stator, gliedern.
