The 3.0-A resolution x-ray structure of human des-Gla-coagulation factor Xa (fXa) has been determined in complex with the synthetic inhibitor DX-9065a. The binding geometry is characterized primarily by two interaction sites: the naphthamidine group is fixed in the S1 pocket by a typical salt bridge to Asp-189, while the pyrrolidine ring binds in the unique aryl-binding site (S4) of fXa ...
