Target type: molecularfunction
Catalysis of the reaction: alpha-maltose + H2O = 2 alpha-D-glucose. [MetaCyc:RXN-2141]
Maltose alpha-glucosidase activity catalyzes the hydrolysis of the alpha-1,4-glycosidic linkage between two glucose molecules in maltose, releasing two glucose molecules. This enzyme is involved in the breakdown of maltose, a disaccharide, into its constituent monosaccharide, glucose. It plays a crucial role in carbohydrate metabolism, allowing the body to utilize maltose as an energy source. The enzyme exhibits specificity for alpha-1,4-glycosidic bonds, and its activity is typically pH-dependent, with an optimal pH range specific to the enzyme. Maltose alpha-glucosidase activity is found in various organisms, including bacteria, fungi, plants, and animals, and it is often associated with digestive processes.'
