KirBac channels are prokaryotic homologs of mammalian inwardly rectifying (Kir) potassium channels, and recent crystal structures of both Kir and KirBac channels have provided major insight into ...

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 ...

Its atomic radius is 0.235 nm and the (+1) ionic radius is 0.133 nm. In the solid state Potassium has a body-centered cubic crystal structure with a = 0.533 nm and a nearest neighbor distance of 0.277 ...

Thomas Blanchard placed potassium phosphate into a dish and photographed the crystallization as it grew into beautiful ...

Metals like potassium are fairly straightforward ... that they could easily predict what might occur to such crystalline structures under pressure. But around 15 years ago, scientists discovered ...
