GENES WHICH ARE RELATED TO DEOXYNOJIRIMYCIN SYNTHESIS, VECTORS AND TRANSFORMNANTS CONTAINING THE GENES AND METHOD OF PRODUCING DEOXYNOJIRIMYCIN USING THEREOF

摘要

PURPOSE: A polypeptide for deoxynojirimycin(DNJ) synthesis is provided to produce a large amount of DNJs using a transformant and to develop an agent for reducing blood glucose. CONSTITUTION: An amino acid sequence for DNJ biosynthesis is denoted by sequence number 10. A nucleic acid molecule relating to DNJ biosynthesis is isolated from Bacillus subtilis sp. A recombinant vector contains the nucleic acid molecules. A host cell is transformed using the recombinant vector. The host cell is yeast, Bacillus subtilis or Escherichia coli. A method for producing polypeptides for DNJ biosynthesis comprises: a step of transforming the host cells with the recombinant vector; and a step of culturing the host cells to collect polypeptides.
