Researchers have established the structure of a crucial enzyme -- the so-called sodium-potassium pump -- which forms part of every cell in the human body. The result may pave the way for a better ...

Figure 4: Interactions among the α- and β- subunits and the FXYD protein at the extracellular surface of the membrane. The role of the signature motif FXYD appears clear (Fig. 4). The first residue, ...

The structure of the sodium-potassium pump is presented in a schematic cell membrane. The extracellular space is situated above and the intracellular space below the figure. The left-hand side of the ...

It's not visible to the naked eye and you can't feel it, but up to 40 per cent of your body's energy goes into supplying the microscopic sodium-potassium pump with the energy it needs. The pump is ...
