1.11.2.4 additional information Bacillus subtilis P450BSbeta produces both the beta-OH (60%) and the alpha-OH (40%) fatty acids. Ferredoxin, ferredoxin reductase, and P450 reductase systems do not appear to function in P450BSbeta reactions. P450BSbeta does not require any electrons and protons for catalytic activity, because it utilizes H2O2 as an oxidant instead of O2/2e-/2H+. This enzyme requires neither a reductase nor a proton delivery system ?
