Gluconobacter oxydans DSM 2343 is known to catalyze the oxidation of glucose to gluconic acid, and subsequently, to 2-keto-D-gluconic acid (2-KGA) and 5-keto-D-gluconic acid (5-KGA), by membrane-bound and soluble dehydrogenases. In G. oxydans MF1, in which the membrane-bound gluconate-2-dehydrogenase complex

The chromosomal locus NP_636946 of Xanthomonas campestris DSM 3586 (ATCC 33913) which was earlier presumed to encode a quinoprotein glucose dehydrogenase has been cloned, expressed in Escherichia coli and the recombinant enzyme has been characterised. It was found to have

We isolated thermotolerant Gluconobacter strains that are able to produce 5-keto-d-gluconic acid (5KGA) at 37 degrees C, a temperature at which regular mesophilic 5KGA-producing strains showed much less growth and 5KGA production. The thermotolerant strains produced 2KGA as the major

Gluconate:NADP 5-oxidoreductase (GNO) from the acetic acid bacterium Gluconobacter oxydans subsp. oxydans DSM3503 was purified to homogeneity. This enzyme is involved in the nonphosphorylative, ketogenic oxidation of glucose and oxidizes gluconate to 5-ketogluconate. GNO was localized in the cytoplasm, had

For easy measurement of 5-keto D-gluconate (5KGA) and 2-keto D-gluconate (2KGA), two enzymes, 5KGA reductase (5KGR) and 2KGA reductase (2KGR) are useful. The gene for 5KGR has been reported, and a corresponding gene was found in the genome of Gluconobacter
