Study reveals structures of six states of a rotary sodium ion pump

Six structures exhibited by the rotating sodium ion pump were reconstructed in 3D using cryo-electron microscopy. This analysis revealed that the rotor exhibits non-uniform rotation behavior due to partial structural interference ...

Unwinding the world's smallest biological rotary motor by degrees

Adenosine triphosphate (ATP) is the energy currency of cells. It powers various cellular processes that require energy, including enzymatic reactions. ATP is synthesized with the help of an enzyme complex called F-type ATP ...

First electric nanomotor made from DNA material

A research team led by the Technical University of Munich (TUM) has succeeded for the first time in producing a molecular electric motor using the DNA origami method. The tiny machine made of genetic material self-assembles ...

Mitochondria efficiently adapt to changing metabolic conditions

A recent study explains an essential component for proper mitochondrial function: The protein complexes MICOS and ATP synthase can communicate with each other. Dr. Heike Rampelt and Prof. Dr. Nikolaus Pfanner at the Institute ...
