EC 2.7.1.232

Accepted name: levoglucosan kinase

Reaction: ATP + levoglucosan + H2O = ADP + D-glucose 6-phosphate

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

Systematic name: ATP:1,6-anhydro-β-D-glucopyranose 6-phosphotransferase (hydrolyzing)

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. The enzyme, found in yeast and fungi, requires a magnesium ion. cf. EC 1.1.1.425, levoglucosan dehydrogenase.
