abstract：:The recombinant amylosucrase from Neisseria polysaccharea was used to glucosylate glycogen particles in vitro in the presence of sucrose as the glucosyl donor. The morphology and structure of the resulting insoluble products were shown to strongly depend on the initial sucrose/glycogen weight ratio. For the lower rati...
