| Accepted Name |
| N-acetylhexosamine 1-kinase. |
| Alternative Name(s) |
| N-acetylgalactosamine/N-acetylglucosamine 1-kinase. |
| Reaction catalysed |
| ATP + N-acetyl-D-hexosamine <=> ADP + N-acetyl-alpha-D-hexosamine 1-phosphate |
| Cofactor(s) |
| Mg(2+). |
| Comment(s) |
- 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 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.
