Fig. 3. Binding interactions of DX-9065a with fXa. The C^
plot
and side chains involved in inhibitor binding of DX-9065a-bound^
fXa (yellow) are superimposed with the corresponding atoms of^
arginine-bound fXa (turquoise). The ligand-induced structural
changes at the S1-binding site may be seen at the side chain of^
Asp-189 and along the main chain at Gln-192. The hydrophobic
sleeve^ at the aryl-binding site (S4) is also apparent, with the
cation hole formed by Glu-97 and the carbonyl oxygens of Glu-97
and Lys-96^ at the back.
