Keratinases have been reported to degrade Prions PrPSc, the infective protein molecules responsible for scrapie, bovine spongiform encephalopathy (BSE or “mad cow disease”), kuru, chronic wasting disease, and Creutzfeldt–Jakob disease (CJD) (Caughey 2001). Studies have revealed the capability of keratinolytic enzymes to degrade this abnormal molecule which suggests their application in drug formulation and as a disinfectant for medical instruments suspected to be contaminated by this protein. Mitsuiki et al. (2010) reported the remarkable degradation of PrPScprotein by keratinase of Nocardiopsis strain TOA-1. Also, the combined action of γ -glutamyl transpeptidase-glutathione and keratinase effectively hydrolyzed surrogate prion protein (Sharma and Gupta 2012).
