| abstract |
The present invention relates to a polypeptide associated with the biosynthesis of 1-deoxynojirimycin which is a substance that inhibits α-glucosidase activity, to a polynucleotide coding therefor, to a vector comprising the polynucleotide, to a transformant comprising the vector, and to a method in which the transformant is used in order to produce either a polypeptide associated with the synthesis of 1-deoxynojirimycin or 1-deoxynojirimycin. The polynucleotide of the present invention can be used in the volume production of 1-deoxynojirimycin, or can be used in studies searching for novel 1-deoxynojirimycin derivatives using recombinant technology, and hence is useful in developing pathogenic virus inhibitors and hypoglycemic agents for diabetic patients. |
