Difference between protease and proteinase?
Proteases: Any of various enzymes, including the endopeptidases and exopeptidases, that catalyze the hydrolytic breakdown of proteins into peptides or amino acids. Poteinases: A protease that begins the hydrolytic breakdown of proteins, usually by splitting them into polypeptide chains. It is also a synonym of endopeptidases (e.g. pepsin, trypsin, or papain). Note: Protease - endo- & exo- peptidases; Catalyze hydrolytic breakdown Proteinase - endo-peptidases; Begins hydrolytic breakdown by splitting
Is protease an enzyme?
Yes, protease is an enzyme that breaks down proteins into smaller peptides or amino acids. It is involved in various cellular processes, including digestion, protein signaling, and recycling of damaged proteins.
Is proelastase activated to elatase?
Yes, proelastase is activated to elastase through cleavage by enzymes like proteinase 3 or cathepsin G. Elastase is a serine protease that plays a key role in breaking down elastin, an important component of connective tissue.
What is the function of Proteinase K in DNA extraction?
Proteinase K is most often used in extracting DNA from while blood cells (or leukocytes). The first step in DNA isolation is to break open the cell and release the cytoplasmic contents, which includes the nucleus, in which we find DNA. Proteinase K is a protease (an enzyme capable of digesting proteins). It is used to digest the cell surface proteins. When cell surface proteins are digested, the integrity of the cell membrane is compromised leading to cell lysis (or the breaking open of the cell)
How proteinase k work?
Proteinase K is a serine protease that cleaves peptide bonds in proteins, facilitating their degradation. It operates effectively in a wide range of temperatures and pH levels, making it useful for various applications, including DNA and RNA extraction. By breaking down proteins, it helps to eliminate contaminants and inhibitors that could interfere with downstream molecular biology processes. Additionally, its activity is enhanced in the presence of detergents, which aid in the lysis of cellular membranes.
What is an antiproteinase?
An antiproteinase is an inhibitor of proteinase activity.

How do you remove proteins that may contaminate the DNA?
To remove proteins that may contaminate DNA, a common method involves using a proteinase, such as proteinase K, which digests proteins in the sample. Following the protease treatment, an organic extraction method, typically using phenol-chloroform, can be employed to separate proteins from DNA. The DNA is then precipitated using alcohol, such as ethanol or isopropanol, allowing for the purification of the nucleic acid. Finally, the DNA is washed with alcohol to remove any remaining contaminants before resuspension in a suitable buffer.
What is the formula for protease?
Protease is an enzyme. It is essentially a protein. Protease is not a compound and therefore its formula cannot be given out. Protease are a class of enzymes involved in digesting proteins. The basic mode of action can be described as: Protein + Protease -----> Digested protein + protease Since enzymes do not react in a biochemical reaction (they are merely catalysis), protease appears on both sides of the reaction shown above
What is the function of proteinase?
This an enzyme which helps to break down proteins.
What has the author Edward A Fox written?

What does protease producE?
Protease breaks down Protein into amino acids
