Figure 4.
(A) Superposition of enantiomer 15h (blue) with the crystal structure of 15g-bound (yellow) PLpro. (B) Docked alignment of the gem-dimethyl substituted compound in the 15g-ligand removed PLpro crystal structure. The bumping collision of one of the methyl groups of the gem-dimethyl (magenta) 15k with the Asp-165 carboxylate is noted.
