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.
