Figure 2

A, crystal structure of rat DT-diaphorase. Pro187 is shown in white. A Pro187 to Ser mutation would disturb the structure of the central parallel β-sheet (yellow), resulting in a reduction in the binding affinity of FAD (green). B, predicted binding orientation of CB1954 (shown in colors according to the atom type). The sites of mutation are shown in purple. C, predicted binding orientation of dicoumarol. D, predicted binding orientation of chrysin. E, predicted binding orientation of phenindone.
