amilo14glükaan4glükanaaltransferaas

Amilo14glükaan4glükanaaltransferaas is an enzyme. It belongs to the glycoside hydrolase family, specifically the GH13 family, also known as the alpha-amylase family. This enzyme plays a role in the breakdown of complex carbohydrates. Its primary function is to catalyze the transfer of a maltooligosaccharide unit from a donor molecule to an acceptor molecule. This process is a key step in the hydrolysis of starch and related polysaccharides.

The enzyme acts on alpha-linked glucans, such as starch, glycogen, and various maltooligosaccharides. It cleaves specific alpha-1,4 glycosidic bonds within these substrates. The transfer reaction involves taking a segment of a polysaccharide chain and attaching it to another molecule, which can be water (leading to hydrolysis) or another carbohydrate chain. This activity is crucial in carbohydrate metabolism and energy mobilization in various organisms.

Amilo14glükaan4glükanaaltransferaas has been identified in a range of species, including bacteria, fungi, and plants. The specific substrate specificity and catalytic efficiency can vary depending on the source of the enzyme. Research into this enzyme and its relatives contributes to our understanding of enzymatic mechanisms involved in polysaccharide degradation and has potential applications in biotechnology, such as in the food industry for starch processing or in the development of biofuels.
