ID   2.7.1.162
DE   N-acetylhexosamine 1-kinase.
AN   N-acetylgalactosamine/N-acetylglucosamine 1-kinase.
CA   ATP + N-acetyl-D-hexosamine = ADP + H(+) + N-acetyl-alpha-D-hexosamine
CA   1-phosphate.
CC   -!- Involved in the lacto-N-biose I/galacto-N-biose degradation pathway
CC       in the probiotic bacterium Bifidobacterium longum.
CC   -!- Differs from EC 2.7.1.157 as it can phosphorylate both
CC       N-acetylgalactosamine and N-acetylglucosamine at similar rates.
CC   -!- Also has some activity with N-acetyl-D-mannosamine, D-talose and
CC       D-mannose as substrate.
CC   -!- ATP can be replaced by GTP or ITP but with decreased enzyme activity.
