|Figure 8: Allosteric network in AR antagonism. A) AR-1881 complex
(PDB 1E3G), showing how
agonists (such as R1881) interact
stably with W741. Dashed lines
indicate the proposed movement
of W741 and H874 in the
absence of a stable interaction.
B) Antagonist HFT is modeled in
wildtype AR pocket. With no
ligand interaction, Duan et al
propose that W741 would swing
over, pushing H874 to hydrogen bond with backbone of I899. This
interaction disrupts the H12 conformation, in a proposed mechanism of antagonism .
