Tuning the Regio- and Stereoselectivity of CH Activation in n-Octanes by Cytochrome P450 BM-3 with Fluorine Substituents: Evidence for Interactions Between a CF Bond and Aromatic π Systems
n‐octane oxidation. In addition, the alanine at residue 328 was replaced with a phenylalanine to introduce an aromatic residue into the hydrophobic pocket to examine whether or not van der Waals interactions between a CF substituent in the substrate and the polarizable π system of the phenylalanine may be used to steer the positioning of the substrate within the active‐site pocket of the enzyme and control
