We tried to analyze the keratinolytic properties of the PrPSc- degrading enzyme E77. E77 showed a much greater keratinolytic activity than proteinase K and subtilisin. The maximum activity of keratin was observed at a pH value of 12.0 at 65°C. E77 also showed a pH-independent adsorbability for keratin. These profiles of E77 were the same as the PrPSc -degrading enzyme NAPase, except for high alkaline conditions. E77 and NAPase showed lower collagenolytic and elastinolytic specificities.}, pages = {37--42}, title = {Keratinolytic Properties of PrPSc-degrading Enzyme E77}, volume = {59}, year = {} }
