Target type: molecularfunction
Catalysis of the transfer of an L-fucosyl group from GDP-beta-L-fucose to an acceptor molecule to form an alpha-(1->3) linkage. [GOC:ai]
Alpha-(1-u003e4)-glucosidases are a family of enzymes that catalyze the hydrolysis of alpha-(1-u003e4) glycosidic bonds in polysaccharides. These enzymes play crucial roles in various metabolic pathways, including carbohydrate digestion, glycogen breakdown, and starch metabolism. The catalytic mechanism involves the formation of a covalent glycosyl-enzyme intermediate, which is subsequently hydrolyzed to release the free sugar. Alpha-(1-u003e4)-glucosidases exhibit substrate specificity, with some enzymes preferentially cleaving linear chains while others act on branched structures. They are also regulated by factors such as pH, temperature, and the presence of inhibitors. The activity of alpha-(1-u003e4)-glucosidases is essential for maintaining cellular energy homeostasis and ensuring the availability of glucose for metabolic processes. Notably, certain alpha-(1-u003e4)-glucosidases are targeted by drugs used to treat type 2 diabetes, inhibiting glucose absorption from the gut and lowering blood sugar levels.'
