Gluconobacter oxydans DSM 4025 effectively oxidizes L-sorbose to 2-keto-L-gulonic acid (2 KGA), an industrial precursor of vitamin C. From this microorganism, we purified the enzyme involved in this oxidation reaction. The enzyme is a unique quinoprotein dehydrogenase catalyzing not only the conversion of L-sorbose to L-sorbosone, but also that of L-sorbosone to 2 KGA. The molecular weight of the enzyme was about 135,000, consisting of two subunits with molecular weights of 64,500 and 62,500… CONTINUE READING
