IUBMB Enzyme Nomenclature


Accepted name: glucosamine kinase

Reaction: ATP + D-glucosamine = ADP + D-glucosamine 6-phosphate

Glossary: D-glucosamine 6-phosphate = 2-amino-2-deoxy-D-glucose 6-phosphate

Other name(s): glucosamine kinase (phosphorylating); ATP:2-amino-2-deoxy-D-glucose-6-phosphotransferase; aminodeoxyglucose kinase; ATP:D-glucosamine phosphotransferase

Systematic name: ATP:D-glucosamine 6-phosphotransferase

Comments: The enzyme is specific for glucosamine and has only a minor activity with D-glucose. Two unrelated enzymes with this activity have been described. One type was studied in the bacterium Vibrio cholerae, where it participates in a chitin degradation pathway. The other type has been described from actinobacteria, where it is involved in the incorporation of environmental glucosamine into antibiotic biosynthesis pathways. cf. EC, ADP-specific glucose/glucosamine kinase.
