| abstract |
The present invention relates to a novel sucrose isomerase capable of producing a large amount of trehalulose from sucrose, a polynucleotide encoding the sucrose isomerase, an expression vector comprising the polynucleotide, an expression vector containing the polynucleotide, And a method for producing the novel sucrose isomerase using the transformant and the transformant. The sucrose isomerase provided in the present invention can produce trehalulose from sucrose in a larger amount than isomaltulose, and thus it can be widely used in the development of sweeteners using trehalulose. |
