The Naming and Characteristics of Restriction Endonucleases

Restriction enzymes, also known as restriction endonucleases, are enzymes that cut double-stranded DNA. Its cutting method is to cut the bond between the carbohydrate molecule and the phosphoric acid, and then create a nick on each of the two DNA strands without damaging the nucleotides and bases.

Detailed Introduction to Common Enzymes Used in Gene Cloning

The basic technology of genetic engineering is artificial cutting, splicing, and a combination of genes. A gene is a DNA molecule with a certain function. To accurately cut out the DNA linear molecular fragments of different genes, various restriction endonucleases are required.

An Overview of the Lipase and Its Industrial Applications

Lipase, also known as glyceride hydrolase, is a glycoprotein composed of 2%-15% sugar bases, the basic unit of which is mannose. Lipase exists in fat-containing animal, plant and microbial (such as mould, bacteria, etc.) tissues.

Which Enzyme Preparations Are Often Used in Fruit and Vegetable Processing?

The so-called fruit and vegetable processing means to maximize the nutrient content of the fruit and vegetable through various processing methods, improve the edible value, and make the color, aroma and taste of the processed product more perfect.

Introduction to Classification and Application of Cellulase

The optimum pH of cellulase is generally 4.5 to 6.5, which acts on cellulose and products derived from cellulose. Microbial cellulase is of great significance in converting insoluble cellulose into glucose and destroying cell walls in fruit and vegetable juice to improve the yield of juice.

The Role and Application of Lipase in Bakery Products

As the effect and safety of enzyme preparations in flour improvement are increasingly recognized by the flour industry and food industry, people have a more and more in-depth understanding of its practicality. As an important member of the family of enzyme preparations, lipase has been recognized by the majority of users for its application effects in whitening, fine tissue, and improvement of the skin of pasta products. There are three main lipases used in bakery products, namely triglyceride lipase, phospholipase and galactose lipase.

Microbial Enzyme Preparations Have a Bright Future in the Food Industry

The microbial enzymatic method is the main way to obtain enzyme preparations in modern enzyme engineering. Except for a few enzymes that are still extracted from animals and plants, most of them are produced by microorganisms.

What is Restriction Endonuclease?

Restriction enzymes have extremely high specificity. They recognize specific sites on double-stranded DNA and cut both strands to form sticky or blunt ends. Restriction enzymes can be used to dissect delicate DNA molecules, and are indispensable tools in the analysis of chromosome structure, DNA restriction enzyme map, determination of longer DNA sequences, gene isolation, and in vitro recombination of genes.

Everything You Want to Learn About Restriction Enzymes

Restriction endonucleases (also known as restriction enzymes) were first found in bacteria, but later they were also found in some archaea. Usually, restriction endonucleases cut double-stranded DNA. Each restriction endonuclease will recognize specific DNA sequence.

Biochemical and Clinical Applications of Glucose Oxidase (GOD)

Glucose oxidase (GOD) is a typical oxidoreductase found in honey and moulds such as Penicillium notatum. It can highly specifically catalyze the β-D-glucose reaction to generate gluconic acid, which has the function of converting glucose and removing oxygen. Since GOD can quantitatively generate hydrogen peroxide, it is widely used in the field of biochemistry and clinical examination as a quantitative reagent for D-glucose.

Research Progress on Application of Enzyme Technology in Food Processing

Enzyme technology usually refers to chemical reaction technology mainly through the catalytic conversion of enzymes in a limited reaction vessel. The application of enzyme technologies has been distributed to all walks of life, such as manufacturing, chemical industry, agricultural industry, environmental resource utilization and exploitation, medicine and other fields.

Abzyme, an Important Artificial Synthetic Enzyme

The development of artificial synthetic enzymes is still in the initial stage, and significant progress has been made after several years of effort. The artificial enzyme developed has a catalytic speed close to that of natural enzymes, which means that the speed of chemical reactions can be increased by more than 100 million times (natural enzymes are usually 10 billion to 1000 billion times).

Classification and Function of Lactic Acid Probiotics

Probiotics are a type of beneficial bacteria in the gut and are now mostly used for gut conditioning and health care. However, people now know less about probiotics, and it is difficult for many people to distinguish whether probiotics are good or bad, and they do not know anything about probiotics. However, there are more than 400 types of probiotics in the human body, and the types of probiotics in our common products can even reach about ten. So, what are the differences between different probiotic strains?

Classification and Function of Amylase

Amylase (AMS), also known as 1,4-α-D-glucanohydrolase, is a general term for enzyme that hydrolyze starch and glycogen. The main function of amylase is to break down starch to produce simple sugars such as fructose, maltose, glucose and dextrin. Amylases are also used in food and beverage processing and other industries.
