1. FLO = 4′-hydroxy-flurbiprofen, FLU  =  Flurbiprofen.

2. The following properties differ among the simulated CYP2C9 models.

 a. Solubility (water soluble ‘SOL’ and membrane-bound ‘MEM’ forms).

 b. Structure of the FG loop (with F' and G' helices or extended loop).

 c. Ligand-bound state (apo ‘APO’, product-bound ‘PROD’ and substrate-bound ‘SUBS’ forms).
