Multiplexed measurement of variant abundance and activity reveals VKOR topology, active site and human variant impact
Vitamin K epoxide reductase (VKOR) drives the vitamin K cycle, activating vitamin K-dependent blood clotting factors. VKOR is also the target of the widely used anticoagulant drug, warfarin. Despite VKOR’s pivotal role in coagulation, its structure and active site remain poorly understood. Here, we ...

Vitamin K epoxide reductases (VKOR) constitute a major family of integral membrane thiol oxidoreductases. In humans, VKOR sustains blood coagulation and bone mineralization through the vitamin K cycle. Previous chemical models assumed that the catalysis of human VKOR (hVKOR) starts from a fully redu...

Integral membrane proteins (IMPs), which constitute 50–60% of drug targets, play essen-tial roles in numerous biological processes but remain underrepresented in conventional bottom-up and in structural proteomics owing to their hydrophobicity and resistance to proteolysis. Although advances in IMPs...
