Figure 8From: Interactions of antiparasitic sterols with sterol 14α-demethylase (CYP51) of human pathogensGeometry-optimized pose of 3-O-caffeoyl-20-epikatonic acid. The blue dash arrow represents hydrogen bonding interactions while the blue sphere on the residues denotes level of solvent exposure. Hydrophobic residues are olive green while polar residues are depicted as pink. The purple circles on the atoms/functional groups represent solvent exposure. The molecular surface diagram is shown in Additional file 1: Figure S6.Back to article page
