Figure 4. (a) Stereoview of dicoumarol bound to FRase I, highlighting the trans-conformation of dicoumarol such that the corresponding keto-oxygens of the two coumarols point in opposite directions. Residues within 4 Å from the buried half of dicoumarol are also shown and labeled, highlighting hydrophobic interaction with the inhibitor and protein. (b) A chemical structure of dicoumarol.
