EC 2.7.1.162 Details
EC number
2.7.1.162
Accepted name
N-acetylhexosamine 1-kinase
Reaction
ATP + N-acetyl-D-hexosamine = ADP + N-acetyl-α-D-hexosamine 1-phosphate
Other name(s)
NahK, LnpB, N-acetylgalactosamine/N-acetylglucosamine 1-kinase
Systematic name
ATP:N-acetyl-D-hexosamine 1-phosphotransferase
Comment
This enzyme is involved in the lacto-N-biose I/galacto-N-biose degradation pathway in the probiotic bacterium Bifidobacterium longum. Differs from EC 2.7.1.157, N-acetylgalactosamine kinase, as it can phosphorylate both N-acetylgalactosamine and N-acetylglucosamine at similar rates. Also has some activity with N-acetyl-D-mannosamine, D-talose and D-mannose as substrate. ATP can be replaced by GTP or ITP but with decreased enzyme activity. Requires a divalent cation, with Mg2+ resulting in by far the greatest stimulation of enzyme activity.
