Combined effects of CPR and cyt b5 concentration on the metabolism of (S)-flurbiprofen to 4′-OH-flurbiprofen and H2O2 formed as a result of catalytic uncoupling (CYP2C9 = 100 nM). (A) rate of 4′-OH-flurbiprofen formation. (B) rate of H2O2 formation. CPR concentrations were as follows: 50 nM (●), 100 nM (○), 200 nM (■), 400 nM (□), 800 nM (▼), 1200 nM (△).
