A process for the degradation of keratin, keratinaceous material, collagen or collagenaceous material comprising contacting keratin, keratinaceous material, collagen or collagenaceous material with an enzyme material isolated from a culture of Micrococcus sedentarius. The enzyme material comprises one or more proteases having the ability to degrade keratin, keratinaceous material, collagen or collagenaceous material. The enzyme material is water soluble, non-dialysable through a membrane having a molecular weight cut-off of 10 kDa, has an isoelectric point of 4.6 or 2.7, a molecular weight of 30.3 kDa or 50 kDa, an optimum pH for protease activity at about 8.2 or at about 10.2 and an optimum temperature for protease activity at about 40.degree. C. or 46.degree. C.
