    ..Additionally, Ser119 was identified as a key residue assisting binding of ritonavir-like inhibitors, which emphasizes the importance of polar interactions in the CYP3A4-ligand association. ..

    ..Transient kinetics as a function of ionic strength suggest that, in contrast to the Pdx-P450cam redox couple where complex formation is predominantly electrostatic, the Pdx-Pdr association is driven by nonelectrostatic interactions. ..

    ..Therefore, Trp106, previously shown to be important in the Pdr-to-Pdx and Pdx-to-P450cam electron transfer reactions is in a position to regulate and/or mediate electron transfer to or from the [2Fe-2S] center of Pdx. ..
