Vitamin K epoxide reductase complex subunit 1 is an enzyme that in humans is encoded by the VKORC1 gene.Vitamin K is essential for blood clotting but must be enzymatically activated. This enzymatically activated form of vitamin K is a reduced form required for the carboxylation of glutamic acid residues in some blood-clotting proteins. The product of this gene encodes the enzyme that is responsible for reducing vitamin K 23-epoxide to the enzymatically activated form.
