Application

Application Comment Organism
synthesis development of an efficient biocatalytic production process of cycloamyloses directly from sucrose by use of Synechocystis sp. 4-alpha-glucanotransferase and Neisseria polysaccharea amylosucrase. From one-pot synthesis, the maximum cycloamylose yield of 9.6%, w/w with 0.3 M sucrose is achieved with 10 units/ml of amylosucrase and 0.1 unit/ml of 4-alpha-glucanotransferase at 40°C for a 3 h reaction in a simultaneous dual enzyme reaction mode. The size of linear alpha-(1,4)-glucan is positively related to the cycloamylose productivity by 4-alpha-glucanotransferase in a hyperbolic manner. The dual enzyme reaction converts sucrose directly to cycloamyloses via in situ transient linear alpha-(1,4)-glucan as an soluble intermediate Synechocystis sp.
