Description: Porteinase K (also known as endopeptidase K) is an extracellular endopeptidase isolated from a culture filtrate of the fungus Tritirachium album limber. This fungus is able to grow on Keratin as the sole source of carbon and nitrogen and therefore given the K designation 1. Proteinase K is a member of the class of serine proteases 2. Since the sequence of the polypeptide chain of 279 amino acids in length 3 and the three dimensional structure 4 has a high degree of homology to bacterial subtilisins, Proteinase K is classified as a member of the subtilisin family. Proteinase K has a specific activity of more than 30 U/mg and is thus one of the most active of the known endopeptidases 5 and unspecifically hydrolyses native and denatured proteins. Active Product: Yes Appearance: Lyophilized powder
