Proteinase K is often a really Energetic serine protease (MW 28,500 Da) isolated in the fungus Tritirachium album. The enzyme reveals broad cleavage specificity on indigenous and denatured proteins which is commonly used in the purification of indigenous RNA and DNA from tissues or cell strains.
It has a shelf lifetime of twelve months when stored within a dry location at 4–eight°C, on account of The truth that it is a really secure. Temporary storage at ambient temperatures tend not to damage the enzyme’s activity and balance.
It is usually utilized for powerful digestion of structural proteins, chromatins, and inactivation of nucleases and RNases.
Proteinase K contains a catalytic triad of a few amino acids – aspartate, histidine, and serine. The serine acts like a nucleophile that cleaves peptide bonds. Calcium ions are crucial for complete enzymatic exercise.
Proteinase K is really a wide-spectrum serine protease which will break down a variety of proteins. It is often used in molecular biology and biochemistry apps to digest structural proteins and enzymes.

). Proteinase K can digest native keratin (hair), as a result the title Proteinase “K”. The predominant website of cleavage is definitely the peptide bond adjacent to your carboxyl group of aliphatic and aromatic amino acids with blocked alpha amino groups.
Moreover, nucleases (enzymes that break down nucleic acids) might be present, the addition of proteinase K degrades these nucleases and protects the nucleic acids from nuclease assault.
This solution is available with the Promega Helix onsite stocking system. We provide numerous practical solutions to fulfill your lab's needs.
Additionally, the FDA authorised PARP inhibitors for instance olaparib and atezolizumab to be used in combination with chemotherapies, primarily to make improvements to their effectiveness and decrease adverse patient outcomes.
