Native ovoperoxidase exhibited an optical absorption spectrum with certain similarities to lactoperoxidase, but not horseradish peroxidase, over the pH range 4.5-11.5. Ovoperoxidase had three distinct spectral forms dependent on pH, with transitions at apparent pKa values of 6.6 and 3.0. Complexes of ovoperoxidase with CN-, N3-, F-, or when reduced and ligated to carbon monoxide, CN-, or pyridine, were distinct from other peroxidases. Ovoperoxidase formed two specific and different spectral… CONTINUE READING
