Figure 3.
Fig. 3. Interactions of compound 1 with the amino acid
residues in the corresponding PR-binding pocket. (A) Binding of
compound 1 molecule Cb1 by PR monomer A (red tube). (B) Binding
of compound 1 molecule Cb2 by PR monomer B (blue tube). Compound
1 is represented by a stick model in gray, with cobalt shown as
a magenta sphere. PR residues in contact with compound 1 are
represented by stick models, and their solvent-accessible
surfaces are colored by atom charge (blue, positive; red,
negative). (C) Superposition of the two compound 1-binding
modes. The color scheme and representation for PR is the same as
in A and B, and atoms in compound 1 are colored with the color
of the interacting PR chain.
