Figure 5. Electrostatic Protein-membrane Interactions in a Snf7 Filament.
(A) A Snf7 protofilament in ribbons placed on a lipid membrane in spheres (grey) (Heller et al., 1993). (B) Electrostatic surface potential showing the membrane interacting surface of a Snf7protofilament with positively charged regions in blue (+10kcal/e-) and negatively charged regions in red (-10kcal/e-).
