New pieces to an old puzzle: identifying the warfarin-binding site that prevents clotting

Warfarin has been the most widely prescribed anticoagulant for decades. It functions by inhibiting the membrane enzyme vitamin K epoxide reductase (VKOR), but the molecular details of this effect have remained elusive. Two new studies shed light on the warfarin-VKOR interaction. The work has implications for precision medicine and could guide drug discovery.
