B>Fig. 2. Virtual Museum of Minerals and Molecules display of the potassium transport channel, organized as a short, narrow pore to select potassium and hydrophobic alpha helices to embed in lipid membranes, connecting the external soil environment to the intracellular milieu. This, the first transmembrane protein resolved in 3-D (1998) and aquaporin (2000, not shown), were both added to the Virtual Museum within months of their initial publication and have been subsequently downloaded thousands of times; their discoverers were jointly awarded the Nobel Prize in Chemistry in 2003.
