Protease Proteins

Endopeptidase is widely used in industry. Endopeptidase is to cut large molecular weight polypeptides into small molecular weight prions and peptones inside the protein molecule, while exopeptidase is to hydrolyze the peptide bond on the free carboxyl group or amino group from the outside (that is, at the end of the protein molecule) to form amino acids. Therefore, exopeptidase can be divided into carboxyl peptidase and aminopeptidase. According to the optimal PH value of protease reaction, it can also be divided into acid protease, neutral protease and alkaline protease.

Protease Proteins FAQs

  • Q

    What is a protease protein?

    Protease is the general term for a class of enzymes that hydrolyze protein peptide chains. It can be said that the protein is broken into smaller polypeptides or single amino acids to promote the formation of new protein products. It mainly hydrolyzes polypeptide bonds in proteins by breaking covalent bonds. It plays a role in a variety of biological functions, including digestive proteins, protein metabolism and cell signaling.

  • Q

    What is the fuction of protease protein?

    Proteases play many roles in physiology, biochemistry and cell or organism. Proteases can destroy protein polypeptide bonds. According to their functions, they can be divided into acidic, neutral and alkaline proteases and are widely distributed in plants, animals and microorganisms. Even in a variety of conditions, such as high salt, high temperature and strong ion environment, they all exist. For example, trypsin has an anti-tumor activity for screening natural drugs in vitro. In sample treatment, alkaline phosphatase can remove the soft tissue of bone samples. In food, flavor protease, protamex and papain have the potential to decompose fungus food to produce different tastes and nutritional values. In the process of pretreatment against myocardial ischemia-reperfusion injury, inhibition of calpain activity can protect the intimal membrane of the cardiac tube. It can reduce the cell membrane damage of ischemia-reperfusion myocardium.
