Oxidation Of 2,5-Diketogluconate by a Cell-free Enzyme Preparation from Acetobacter Melanogenum


IT has been reported by Katznelson et al. 1 that ‘old’ intact cells and cell-free extracts of Acetobacter melanogenum oxidize glucose to gluconate, 2-ketogluconate and finally to 2,5-diketogluconate. We have obtained evidence that this last compound can be oxidized further.
