Description
Proteinase K, also known as keratinase, is derived from microorganisms that digest hair and keratin. This product is engineered through protein engineering, with the gene originating from Engyodontium album, a strain of Rhizopus that has been optimized through site-directed mutagenesis. The gene is then expressed and purified through recombinant yeast expression.
Our Mutant Proteinase K (Industrial Grade) boasts higher specific activity and a broader temperature range (4-85°C) as well as a wider pH activity range (pH 4-12). Advanced protein engineering techniques combined with large-scale yeast cultivation platforms effectively reduce the unit cost, making it the most cost-effective proteinase K option for biopharmaceutical research and production enterprises.
Our Mutant Proteinase K is among the most active proteinases available, with an optimal pH range of 4-12 and a temperature range of 4-85°C. Its activity remains unaffected in the presence of SDS, urea, or EDTA. Its mechanism involves cleaving peptide bonds at the carboxyl end of both aliphatic and aromatic amino acids, enabling the degradation of all proteins into peptides and amino acids. It can effectively replace other protease family products such as alkaline proteases, acidic proteases, neutral proteases, papain, and bromelain, simplifying industrial processes and reducing production costs.
Our company primarily produces molecular biology-grade Mutant Proteinase K, commonly used in gene diagnostic kits, genome DNA extraction kits, and RNA extraction kits to remove nucleases and other protein contaminants.
