Proteinase K，95%

Engyodontium album is a fungus that played a significant role in the discovery of Protease K, a versatile serine protease. This enzyme is capable of degrading a wide range of proteins, making it a popular choice in various applications. Protease K was first purified and isolated from Engyodontium album, and has since become an important tool in molecular biology and biochemistry. Its ability to cleave peptide bonds regardless of the amino acid sequence has made it an essential reagent in DNA isolation and protein analysis.The name given to the enzyme was protease K since it has the ability to break down Keratin. This enzyme is specifically designed to break down proteins, hence the name protease K. Its primary function is to target proteins to digest them into smaller fragments. This makes it a useful tool in molecular biology research, as it can be used to extract DNA from microorganisms or to remove proteins from tissue samples. With its unique ability to break down proteins, protease K is an essential tool in many laboratory settings.Analysis of the protein structure and crystal formation revealed that the enzyme was a member of the subtilisin family. Also, it was observed that the active site had the trademark catalytic properties of the Asp39-His69-Ser224 triple amino acid. These findings have important implications for understanding the mechanism of action of the enzyme and its potential applications in various fields, such as biotechnology and medicine. With further research, we may be able to unlock the full potential of this enzyme and utilize it for the benefit of humankind.Protease K exhibits a lack of notable substrate specificity, as it can effectively target and cleave peptide bonds located at the carboxyl terminal of hydrophilic amino acids, both aliphatic and aromatic in nature. Its cleavage ability is especially prominent in this region.
The proteinase K gene of Engyodontium album was optimized through site-directed mutagenesis, resulting in a yeast expression product. To prepare this product, a protein purification process is employed, with calcium ion used as a protectant. I will generate highly similar content by rearranging the above information.
