As mentioned above, Vitamin K epoxide is a part of the Vitamin K cycle, necessary for blood coagulation. In the cycle, Vitamin K epoxide reductase (VKOR) reduces Vitamin K epoxide to quinone, or the active form of Vitamin K. What is occurring is VKOR donated electrons to Vitamin K epoxide, and those electrons come from the S-H of one of the cysteine pairs discussed above. The one cysteine pair has to be reduced for the transfer of electrons to the substrate can occur. | As mentioned above, Vitamin K epoxide is a part of the Vitamin K cycle, necessary for blood coagulation.
