It was shown to belong to the genus Arthrobacter and tentatively named Arthrobacter sp. I-552. A novel enzyme catalyzed the dehydrogenation of levoglucosan to form 1,6-anhydro-beta-D-ribo-hexopyranos-3-ulose (3-keto levoglucosan), using NAD+ as an electron acceptor, i.e. NAD+: 1,6-anhydro-beta-D-glucopyranose oxidoreductase (trivial name: levoglucosan dehydrogenase). This enzyme was purified and characterized. A possible reaction scheme for the glucose formation was proposed. This pathway for levoglucosan use is distinct from those in yeast and fungi. Levoglucosan dehydrogenase involved in the assimilation of levoglucosan in Arthrobacter sp.
