Recombinant Proteinase K is a stable serine protease with broad substrate specificity. It degrades many proteins in the native state even in the presence of detergents (1% Triton or 0.5% SDS). Proteinase K was isolated from a fungus (Engyodontium album, formerly Tritirachium album) and expressed in Pichia pastoris. Is able to grow on keratin and the enzyme can digest native keratin(hair), hence, the name “Proteinase K”. NZYtech Proteinase K is a highly stable enzyme with an optimum temperature of 50-56 °C (activity range 20-65 °C) and optimum pH of 7.5-8.5 (activity range 4.0-12.0). Proteinase K is frequently used in molecular biology applications to digest unwanted proteins, such as nucleases from DNA or RNA preparations from microorganisms, cultured cells and plants.
