Fig. 5 A highly positive surface of YLSCP2. Above, two opposite faces (a 180º rotation about a vertical axis in the plane of the paper) of YLSCP2 colored according to the electrostatic potential (from blue +5 kT/e to red -5kT/e). Below, a cartoon representation of the above molecular orientations. The liganded palmitate is shown as van der Waals spheres.
