WebAug 28, 2012 · We report the high-resolution (1.9 Å) crystal structure of oligomycin bound to the subunit c (10) ring of the yeast mitochondrial ATP synthase. Oligomycin binds to the surface of the c (10) ring making contact with two neighboring molecules at a position that explains the inhibitory effect on ATP synthesis. WebThe ATP synthase, also called Complex V, has two major subunits designated F 0 and F 1. The F 0 part, bound to inner mitochondrial membrane is involved in proton translocation, whereas the F 1 part found in the mitochondrial matrix is the water soluble catalytic domain.
WebJan 24, 2024 · Uncoupling agents, such as aspirin and 2,4-dinitrophenol, dissociate the electron transport chain from ATP synthesis by reducing the electrochemical gradient across the mitochondrial membrane. Oligomycin inhibits ATP synthesis by blocking the reflux of protons through ATP-synthase. WebOligomycin has long been known as an inhibitor of mitochondrial ATP synthase, putatively binding the F(o) subunits 9 and 6 that contribute to proton channel function of the complex. As its name implies, OSCP is the oligomycin sensitivity-conferring protein necessary for the intact enzyme complex to …
WebSep 5, 2024 · Oligomycin inhibits ATP synthase. [23] [24] Rotenone (and some barbiturates) – inhibits complex I (coenzyme Q binding site) Rotenone is a broadly used pesticide, but more often in the US as a piscicide (fish). Rotenone blocks complex I from passing electrons from the Fe-S clusters to ubiquinone.
WebOligomycin has been shown to block the flow of protons required to drive the F1 F 0 -ATPase by binding to the oligomycin sensitivity-conferring protein (OSCP) within the F 0 subunit found in the stalk of the ATP synthase structure ( Figure 4 ). 175 Oligomycin has been used to probe tumor cell dependence on glycolytic metabolism, 176 the effect of … shares cbaWebOligomycin, an antifungal antibiotic, is an inhibitor of H+-ATP-synthase.
