D-glucosamine 6-phosphate

The enzyme characterised from Schistosoma mansoni converts the hexose sugar, D-glucosamine (shown in its cyclic form) to D-glucosamine 6-phosphate by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP).[1] Two non-identical enzymes which catalyse the same reaction are known. One from Vibrio cholerae is involved in chitin breakdown.[2] The other, from Actinobacteria is part of biosynthetic pathways to compounds with applications as antibiotics.[3]

This enzyme is a transferase, specifically one transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:D-glucosamine phosphotransferase. Other names in common use include glucosamine kinase (phosphorylating), ATP:2-amino-2-deoxy-D-glucose-6-phosphotransferase, and aminodeoxyglucose kinase.[4]
