Dextrin dextranase
Dextrin Dextranase[edit | edit source]
The structure of dextrin dextranase.
Dextrin dextranase is an enzyme that plays a crucial role in the breakdown of complex carbohydrates known as dextrins and dextrans. It is classified as a glycoside hydrolase enzyme and is commonly found in various microorganisms, including bacteria and fungi. Dextrin dextranase is of significant interest in the food industry due to its ability to modify the texture and viscosity of food products.
Structure[edit | edit source]
The structure of dextrin dextranase consists of a single polypeptide chain folded into a compact globular shape. It typically consists of several domains, including a catalytic domain responsible for the enzymatic activity and various auxiliary domains that aid in substrate binding and stabilization. The catalytic domain contains the active site, where the hydrolysis of dextrins and dextrans takes place.
Function[edit | edit source]
Dextrin dextranase catalyzes the hydrolysis of the α-1,6-glycosidic linkages present in dextrins and dextrans. These complex carbohydrates are commonly found in various food products, such as bread, beer, and confectionery. By breaking down these linkages, dextrin dextranase helps to reduce the viscosity and improve the texture of these food products.
Applications[edit | edit source]
The food industry extensively utilizes dextrin dextranase for various purposes. It is commonly employed in the production of baked goods, where it helps to improve the texture and extend the shelf life of bread. Additionally, dextrin dextranase is used in the brewing industry to enhance the clarity and stability of beer. It is also utilized in the confectionery industry to prevent the crystallization of sugar and improve the mouthfeel of candies.
Production[edit | edit source]
Dextrin dextranase can be produced through fermentation using microorganisms such as bacteria or fungi. The production process involves the cultivation of these microorganisms in a suitable growth medium, followed by the extraction and purification of the enzyme. Various techniques, including chromatography and filtration, are employed to obtain a highly pure and active form of dextrin dextranase.
