Comments
[?]
| FUNCTION | 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. |
| CATALYTIC ACTIVITY | Reaction=D-glucosamine + ATP = D-glucosamine 6-phosphate + ADP + H(+); Xref=Rhea:RHEA:10948, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:58723, ChEBI:CHEBI:58725, ChEBI:CHEBI:456216; EC=2.7.1.8; |
| COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Note=Binds 2 Mg(2+) ions per subunit |
| SUBUNIT | Monomer. |
| SIMILARITY | Belongs to the actinobacterial glucosamine kinase family. |
