  As an important member of CYP1 sub-family, CYP1A2 mediates the metabolisms of approximately 5-10% of the currently clinical medicines, and plays a predominant role in the activation of precarcinogens. F186L mutation in this CYP enzyme is found to have ability to reduce the enzymatic activity. As this mutation is far away from the active site and has no influence on the protein expression, the detailed mechanism for F186L-induced the decrease of the enzymatic activity of CYP1A2 is still unknown. In the current study, we employed molecular dynamics simulation and free energy calculation to study the wild-type and F186L mutant CYP1A2 with a α-naphthoflavone (ANF) bound in the active site. Our simulations showed that instead of changing the backbone structure, the F186L mutation has significant impact on the side-chain conformations, resulting in a .. Read More»
