| Research Abstract |
To evaluate structure‐activity relationship of CYP2C9 genetic variants, CYP2C9*3, CYP2C9*28, CYP2C9*30, found in Japanese, in vitro functional study and X-ray crystallography were performed using recombinant CYP2C9 enzymes. Two variants, CYP2C9.3 and CYP2C9.30 showed decreased catalytic activities toward glyburide. X-ray crystallography revealed that amino acid substitution by CYP2C9*30 might influence the binding of losartan at substrate binding site.
