Cytochrome P450 enzymes (P450s) are a superfamily of monooxygenases that utilize a cysteine thiolate-ligated heme moiety to perform a wide range of demanding oxidative transformations. Given the oxidative power of the active intermediate formed within P450s during their active cycle, it is remarkable that these enzymes can avoid auto-oxidation and retain the axial cysteine ligand in the deprotonated-and thus highly acidic-thiolate form ...
