NOVEL D-SORBITOL DEHYDROGENASE AND METHOD FOR PRODUCING L-SORBOSE USING SAME

摘要

The present invention relates to a D-sorbitol dehydrogenase expressed in a novel D-sorbitol dehydrogenase gene derived from a Gluconobacter oxydans strain having D-sorbitol dehydrogenase activity, a method for preparing D-sorbitol dehydrogenase from a strain transformed into a recombinant expression vector comprising the gene, and a method for producing L-sorbose using the enzyme. A recombinant D-sorbitol dehydrogenase according to the present invention specifically transforms D-sorbitol and can stably catalyze an enzyme reaction. The Gluconobactor oxydans-derived D-sorbitol dehydrogenase and the method for producing L-sorbose using same can be efficiently used for mass production of L-sorbose.
