Proteinase K is a robust serine protease that exhibits a wide range of substrate specificity. It is capable of degrading numerous native-state proteins, even in the presence of detergents. Crystal and molecular structure studies have demonstrated that the enzyme is a member of the subtilisin family, possessing an active site catalytic triad (Asp39-His69-Ser224). The enzyme’s primary cleavage site is the peptide bond adjacent to the carboxyl group of aliphatic and aromatic amino acids with blocked alpha amino groups. It is frequently employed for its broad specificity.

Types of Proteinase Solution
There are several types of Proteinase K Solution, each with different properties and applications. Proteinase K is one of the most commonly used types of Proteinase Solution. It is a broad-spectrum enzyme that can cleave a wide range of proteins. It is also highly resistant to denaturation, which makes it useful in harsh conditions, such as high temperatures and detergents.
Other types of Proteinase Solution include trypsin, chymotrypsin, and papain. Trypsin is a serine protease that cleaves peptide bonds on the carboxyl side of lysine and arginine residues. Chymotrypsin is also a serine protease that cleaves peptide bonds on the carboxyl side of aromatic amino acids. Papain is a cysteine protease that cleaves peptide bonds on the carboxyl side of amino acids with bulky hydrophobic side chains.
How to Use Proteinase Solution
The use of Proteinase Solution depends on the application. In general, Proteinase Solution is added to the sample and incubated for a specific period of time. The optimal conditions for Proteinase Solution depend on the type of enzyme and the sample being used. For example, Proteinase K is commonly used at a concentration of 0.1-1 mg/mL and incubated at 55-60°C for 30-60 minutes.
Storage and Handling of Proteinase Solution
Proteinase Solution should be stored at -20°C or below to maintain its activity. It should also be protected from light and moisture. Before use, Proteinase Solution should be thawed on ice and mixed well to ensure homogeneity. It is also important to use sterile techniques when handling Proteinase Solution to prevent contamination.
