Transketolase mutants derived from Bacillus pumilus IFO 12089 produced two unknown compounds. One of them was isolated from the culture broth and was determined to be a new monosaccharide, 1-deoxy-D-altro-heptulose (1-deoxy-sedoheptulose) (1). Compound 1 was easily converted into its non-reducing anhydride in acidic solution at room temperature, which was identified as 2, 7-anhydro-l-deoxy-β-D-altro-heptulopyranose (2). Compounds 1 and 2 were also chemically synthesized from 2, 7-anhydro-β-D-altro-heptulopyranose (3) to confirm the chemical structures.
