Not the ferryl oxidant? The oxidation of thiafatty acids by P450 BM3 (CYP102A1) was shown to be consistent with oxidation by the ferric hydroperoxy species (Cpd 0) rather than the expected ferryl species (Cpd 1). This is the first indication that sulfur oxidation in a wildtype P450 occurs via the hydroperoxy species. (Chemical Equation Presented).
