It is located in the inner membrane of mitochondria and chloroplast membrane or the plasma membrane of prokaryotic cells. ATP synthesis in oxidative and photosynthetic phosphorylation is catalyzed by the F~ beta subunit using the energy of proton flux across the membranes. Recently, Ohta and Kagawa...
(a) Crystal structure of chicken ASIC1 viewed parallel to the membrane plane. Each subunit of the trimer is shown in ribbon representation of a different colour. The horizontal lines demarcate the limits of the plasma membrane enclosing the transmembrane helices (TM1 and TM2) of the subunits. ...
In order to adapt to changing environments and eventually to survive, cells have to change their shape constantly: they bend, stretch, and move. In doing so, the cells depend on a network of filaments called the cytoskeleton just beneath the plasma membrane, which surrounds the cells. One key...
