[https://www.uniprot.org/uniprot/K0NYR4_9CAUD K0NYR4_9CAUD] [https://www.uniprot.org/uniprot/VKOR1_HUMAN VKOR1_HUMAN] Involved in vitamin K metabolism. Catalytic subunit of the vitamin K epoxide reductase (VKOR) complex which reduces inactive vitamin K 2,3-epoxide to active vitamin K. Vitamin K is required for the gamma-carboxylation of various proteins, including clotting factors, and is required for normal blood coagulation, but also for normal bone development.<ref>PMID:14765194</ref> <ref>PMID:14765195</ref> <ref>PMID:15879509</ref> <ref>PMID:16270630</ref> <ref>PMID:20978134</ref> <ref>PMID:22923610</ref> <ref>PMID:33154105</ref>

== Publication Abstract from PubMed ==
 +
Vitamin K antagonists are widely used anticoagulants targeting vitamin K epoxide reductases (VKOR), a family of integral membrane enzymes. To elucidate their catalytic cycle and inhibitory mechanism, here we report eleven x-ray crystal structures of human VKOR and pufferfish VKOR-like with substrates and antagonists in different redox states. Substrates entering the active site in a partially oxidized state form a cysteine adduct that induces an open-to-closed conformational change, triggering reduction. Binding and catalysis is facilitated by hydrogen-bonding interactions in a hydrophobic pocket. The antagonists bind specifically to the same hydrogen-bonding residues and induce a similar closed conformation. Thus, vitamin K antagonists act through mimicking the key interactions and conformational changes required for the VKOR catalytic cycle.
