ABSTRACT:
D-ketohexose 3-epimerase, a novel epimerase, is obtained by cultivating bacteria of the genus Pseudomonas including Pseudomonas cichorii ST-24 (FERM BP-2736). D-Ketohexose 3-epimerase epimerizes D-ketohexose, D-ketopentose and L-ketopentose at their C-3 positions to form their corresponding epimeric counterparts in a high yield at a high conversion rate. Interconversion reaction using D-Ketohexose 3-epimerase yields mixture of intact ketose and its epimeric counterpart which can impart an appropriate sweetness, gloss and improve taste quality when used in foods, beverages, feeds, pet foods, dentifrice, cachou, sublingual agents and internal medicines.
