CHARACTERIZATION OF POLYPHENOLOXIDASE FROM WILD PEAR (PYRUS ELAEGRIFOLIA)
Journal of Food Biochemistry, 2008 ABSTRACT Wild pear polyphenoloxidase (PePPO) was extracted and purified using a Sepharose 4B-l-tyrosine-p-amino benzoic acid affinity column. Optimum conditions for pH, temperature and heat inactivation were determined. At the optimum pH and temperature, KM and Vmax values for PePPO with catechol and pyrogallol were determined. The Vmax/KM showed that
