Vitamin K Cycle

Vitamin K Epoxide Reductase has a large role in the Vitamin K Cycle. The vitamin K Cycle, and the VKOR enzyme 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.
