IUBMB Enzyme Nomenclature


Accepted name: levoglucosan dehydrogenase

Reaction: levoglucosan + NAD+ = 3-dehydrolevoglucosan + NADH + H+

Glossary: levoglucosan = 1,6-anhydro-β-D-glucopyranose

Other name(s): 1,6-anhydro-β-D-glucose dehydrogenase

Systematic name: 1,6-anhydro-β-D-glucopyranose:NAD+ 3-oxidoreductase

Comments: Levoglucosan is formed from the pyrolysis of carbohydrates such as starch and cellulose and is an important molecular marker for pollution from biomass burning. This enzyme is present only in bacteria, and has been characterized from Arthrobacter sp. I-552 and Pseudarthrobacter phenanthrenivorans. cf. EC, levoglucosan kinase.
