Filming the roundabout production of cells’ chemical fuel
Filming the roundabout production of cells' chemical fuel - Japanese researchers have used a high-speed atomic force microscopy (AFM) to shoot a movie of the tiny rotating enzyme that produces the chemical fuel for cells. There are plenty of still pictures of ATPase, the enzyme that synthesises adenosine triphosphate (ATP), thanks to X-ray crystallography and pulsed-laser methods. However, 'moving' pictures should offer scientists a much clearer view of the enzyme's inner workings.
