DEX49A FROM PENICILLIUM MINIOLUTEUM
Overview
Dextranase catalyzes the hydrolysis of the alpha-1,6-glycosidic linkage in, dextran polymers. The structure of dextranase, Dex49A, from Penicillium, minioluteum was solved in the apo-enzyme and product-bound forms. The main, domain of the enzyme is a right-handed parallel beta helix, which is, connected to a beta sandwich domain at the N terminus. In the structure of, the product complex, isomaltose was found to bind in a crevice on the, surface of the enzyme. The glycosidic oxygen of the glucose unit in, subsite +1 forms a hydrogen bond to the suggested catalytic acid, Asp395., By NMR spectroscopy the reaction course was shown to occur with net, inversion at the anomeric carbon, implying a single displacement, mechanism. Both Asp376 and Asp396 are suitably positioned to activate the, ... [(full description)]
