Glucosamine kinase

UniProtKB accession:  A0A1H7TQR5

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the ATP-dependent phosphorylation of D-glucosamine (GlcN) to D-glucosamine 6-phosphate. May be involved in the phosphorylation of acquired extracellular GlcN derived from the hydrolysis of chitosan, i.e., in the incorporation of exogenous GlcN into the bacterial GlcNAc metabolism. To a lesser extent, is also active on glucose, but is unable to phosphorylate maltose, 18 other sugars and several aminoglycoside antibiotics.
