Vitamin K Epoxide Reductase (VKOR) is an endoplasmic membrane enzyme that generates the active form of Vitamin K to support blood coagulation. The vitamin K Cycle, and the VKOR enzyme specifically are common drug targets for thromboembolic diseases. This is because, as pictured, the vitamin K cycle is the process in which blood coagulant factors II, VII, IX, and X are activated. This promotes blood clotting, which can be dangerous and cause thromboembolic diseases such as stroke, deep vein thrombosis, and/or pulmonary embolism.
