FIGURE 1.
The non-annular binding site for anionic phospholipid on KcsA. The lipid molecule, modeled as diacylglycerol (DAG) in the crystal structure of KcsA, is bound at the interface between monomers 1 and 2, whose surfaces are shaded light and dark gray, respectively. The partial lipid molecule modeled as nonan-1-ol (FA) is also shown (PDF file 1K4C).
