Cholesterol is oxidized by commercially available Pseudomonas fluorescens cholesterol oxidase to 6 beta-hydroperoxycholest-4-en-3-one as the initial product, with none of the expected produce, cholest-4-en-3-one, formed. The transformation indicates that P. fluorescens cholesterol oxidase also acts as a flavoprotein dioxygenase.
