The article "Properties and Applications of Starch-Converting Enzymes of the α-Amylase Family" by Maarel et al. (2002) provides a comprehensive review of the α-amylase family, a group of enzymes that play a crucial role in starch processing and various industrial applications. The α-amylase family is characterized by a (β/α)8 barrel structure, the hydrolysis or formation of glycosidic bonds in the α conformation, and conserved amino acid residues in the active site. These enzymes are involved in the hydrolysis of starch, producing glucose, fructose, and other products, which are essential for the starch industry. The review highlights the diversity of reaction and product specificities within the family, the mechanistic principles deduced from structure-function relationships, and the industrial applications of these enzymes. Key points include: - The α-amylase family enzymes are used in the production of maltodextrins, modified starches, and glucose and fructose syrups. - These enzymes are also used in laundry and porcelain detergents and as anti-staling agents in baking. - The review discusses the industrial production of glucose and fructose from starch, including the use of α-amylases, glucoamylases, and pullulanases. - The baking industry uses α-amylases to improve the texture and volume of baked goods and delay staling. - Cyclodextrin glycosyltransferases are used to produce cyclodextrins, which have various applications in analytical chemistry, agriculture, biotechnology, pharmacy, food, and cosmetics. - The article also covers the engineering of commercial enzymes to improve their stability under extreme conditions, such as high temperatures and pH levels. Overall, the α-amylase family enzymes are essential in the starch industry and have a wide range of applications in various sectors.The article "Properties and Applications of Starch-Converting Enzymes of the α-Amylase Family" by Maarel et al.
