Protein Variants
| Protein Variants | Comment | Organism |
|---|---|---|
| additional information | knockout of endogenous VKOR activity, i.e. VKOR and VKORC1L1 enzymes, in HEK-293 cells by transcription activator-like effector nucleases (TALENs)-mediated genome editing, overview. VKOR knockout cells regained KO reductase activity through VKORC1L1 after culturing for several generations (Figure 3A). In addition, this activity is sensitive to warfarin inhibition as the wild-type cells | Homo sapiens |
Inhibitors
| Inhibitors | Comment | Organism | Structure |
|---|---|---|---|
| warfarin | the oral anticoagulant impairs the synthesis of functional clotting factors through inhibition of VKOR and is widely used for prevention and treatment of thrombosis | Homo sapiens |  |
