The chemical ATP, adenosine triphosphate, is the fuel that powers all life. Despite ATP's central role, the structure of the enzyme generating ATP, F1Fo-ATP synthase, in mammals, including humans, has ...

The mitochondrial adenosine triphosphate (ATP) synthase produces most of the ATP required by mammalian cells. We isolated porcine tetrameric ATP synthase and solved its structure at 6.2-angstrom ...

DNA aptamers are powerful molecular tools in biosensing, bioimaging and therapeutics. However, a limited understanding of their tertiary structures and binding mechanisms hinders their further ...

A so-called "molecular chaperone", the protein Hsp70, carries out more functions in the maturation of proteins than previously thought. As the researchers have discovered, Hsp70 not only acts as a ...

The endogenous inhibitor of ATP synthase in mitochondria, called IF₁, conserves cellular energy when the proton-motive force collapses by inhibiting ATP hydrolysis. Around neutrality, the ...
