  • GENE ENCODING RECOMBINANT TREHALOSE PHOSPHORYLASE, VECTOR CONTAINING THE GENE, TRANSFORMANT TRANSFORMED BY THE GENE, AND METHOD FOR PRODUCING RECOMBINANT TREHALOSE PHOSPHORYLASE WITH THE USE OF TRANSFORMANT
    Publication number: 20020068349
    Abstract: A novel recombinant trehalose phosphorylase is provided. A gene encoding trehalose phosphorylase has been discovered. A vector containing the gene is constructed, a transformant is prepared, and recombinant trehalose phosphorylase is produced using the transformant. Trehalose phosphorylase can be produced in an industrial scale. Trehalose can be manufactured advantageously in an industry scale from D-glucose and &agr;-D-glucose 1-phosphoric acid using this enzyme.

  • Trehalose phosphorylase and preparation thereof
    Patent number: 5643775
    Abstract: This invention provides highly thermally stable trehalose phosphorylases. The trehalose phosphorylases of the present invention can be obtained from cultured mixture of microorganisms and are highly thermally stable, and produce .alpha.-D-glucose 1-phosphate and D-glucose by an action on trehalose and an inorganic phosphoric acid or salt thereof, or trehalose by an action on .alpha.-D-glucose 1-phosphate and D-glucose. This invention also relates to the process for the preparation of trehalose phosphorylase, and trehalose or .alpha.-D-glucose 1-phosphate with said trehalose phosphorylase.
