| classification of protease | protease is a general term for a class of enzymes that hydrolyze protein peptide bonds, so it is also called peptidase. It is the earliest and the most in-depth enzyme research. By the beginning of the 21st century, more than 900 kinds of microbial proteases had been reported, and the physiological activities of organisms and the occurrence of diseases, such as digestion and absorption of food, blood coagulation, hemolysis, anti-inflammation, blood pressure regulation, cell differentiation autolysis, aging, cancer metastasis and activation of physiologically active peptides are all related to proteases. Proteases are widely found in animal viscera, plant stems and leaves, fruits and microorganisms. Microbial protease, mainly by mold, bacteria, followed by yeast, Actinomycetes production. A wide range of protease, according to its source can be divided into animal protease, extracted from animal pancreas, such as pepsin, trypsin, alpha-chymotrypsin; Plant protease, from plant fruit, juice, root, stem and seed extraction, such as papain, bromelain, ficin, etc.; Microbial protease, almost all microbial groups can produce protease, even the same type of microorganisms can produce different types of protease. Microbial protease can be divided into bacterial protease, fungal protease, actinomycete protease. According to the different parts of the protein, it can be divided into endopeptidase and exopeptidase. According to its optimum pH value can be divided into acid protease, neutral protease, alkaline protease. According to the different active center and essential genes, it can be divided into thiol protease, metalloprotease, serine protease, and protease that can only hydrolyze the peptide bond between one or two kinds of amino acids. Important pepsin, trypsin, cathepsin, papain and subtilisin, etc. |
| Use | proteases are usually prepared by fermentation. Its use is very extensive. Food industry (soy sauce brewing, cheese making, bread making, snacks, pasta, meat processing, wine making, protein hydrolysate making, deodorization, amino acid dressing, curd, tender meat powder, etc.); daily Chemical Industry (detergent additives, toothpaste, cosmetics, etc.); Leather industry (hair removal, soft skin); Gelatin; Collagen fiber; Pharmaceutical; Processing waste photographic film; Feed industry, petroleum industry (dewaxing), etc. Figure 1 is the spatial structure of the protease Properties: brown or gray powder, from Aspergillus niger by fermentation from, soluble in water use: biochemical research. Hydrolyzed protein, with strong ability to hydrolyze, can hydrolyze macromolecules of protein into amino acids and other products |
| specificity | proteases have certain specificity requirements for groups adjacent to peptide bonds that they hydrolyze, for example, carboxypeptidase and aminopeptidase respectively require that the peptide bond is adjacent to free carboxyl and amino groups; Chymotrypsin requires that the carboxyl terminus of its hydrolyzed peptide bond is an aromatic amino acid (tyrosine or tryptophan, etc.), trypsin is required to be a basic amino acid (lysine or arginine, etc.). (2016-01-24) |
| protease producing strains | There are many kinds of strains that can be used for large-scale production of protease, such: ① alkaline protease-producing Bacillus licheniformis (Bacillus licheniformis), Bacillus pumilus (B.pumilus), Alkalophilic bacillus (B. Alcalophus, Streptomyces griseus and Streptomyces freundii (S.fradiae), etc.; (2) neutral protease-producing Bacillus subtilis (B.subtilis) and Aspergillus ternicola et al.; (3) acid protease-producing such as Aspergillus niger (A.niger) and Aspergillus uzomeprae (A.usamii), etc. |
| proteolytic mode | The proteolytic mode includes: ① cleavage of peptide bond in protein molecule, to produce polypeptides with smaller molecular weight; ② cleave the peptide bond at the amino or carboxyl terminal of the protein or polypeptide molecule and free the amino acid; ③ hydrolyze the ester bond of the protein or polypeptide; hydrolysis of protein or polypeptide amide bond. |
| preparation method | acid protease is obtained from Aspergillus niger by controlled fermentation process, it can hydrolyze proteins to amino acids and polypeptides at acidic pH. |
