Vitamin K epoxide reductase (VKOR) is the enzyme responsible for regenerating vitamin K from vitamin K epoxide to support blood coagulation.  
Vitamin K epoxide reductase (VKOR) is the enzyme responsible for regenerating vitamin K from vitamin K epoxide to support blood coagulation.  
[[Image:Vitamin_K_Cycle_IJEV.jpg|300 px|left|thumb|'''Figure 1. Vitamin K Cycle''' λ-glutamyl carboxylase uses Vitamin KH2 to carboxylate blood clotting cofactors, converting KH2 to KO in the process. Prothrombin is shown as an example of a blood clotting cofactor that later enters the coagulation cascade. VKOR converts KO back to KH2 via two steps with Vitamin K as an intermediate. ]]
