Aerobic oxidation of p-hydroquinone by horse radish peroxidase in the presence of a thiol and MnCl2.
In the presence of MnCl2 and a thiol (glutathione, cysteine, 2-nitro-5-thiobenzoic acid) horse radish peroxidase oxidizes p-hydroquinone to p-benzoquinone which in turn immediately adds the thiol present yielding 2-S-substituted p-hydroquinone.
