additional information the recombinant amylosucrase is 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 are shown to strongly depend on the initial sucrose/glycogen weight ratio. For the lower ratio (1.14), all glucose molecules produced from sucrose are transferred onto glycogen, yielding a slight elongation of the external chains and their organization into small crystallites at the surface of the glycogen particles. With a high initial sucrose/glycogen ratio (342), the external glycogen chains are extended by amylosucrase, yielding dendritic nanoparticles with a diameter 4-5 times that of the initial particle Neisseria polysaccharea ?
