N-acetylhexosamine 1-kinase from Bifidobacterium longum, Recombinant

N-acetylhexosamine 1-kinase (EC 2.7.1.162, NahK, LnpB, N-acetylgalactosamine/N-acetylglucosamine 1-kinase) is an enzyme with systematic name ATP:N-acetyl-D-hexosamine 1-phosphotransferase. This enzyme catalyses the following chemical reaction: ATP + N-acetyl-D-hexosamine →ADP + N-acetyl-alpha-D-hexosamine 1-phosphate. This enzyme is involved in the lacto-N-biose I/galacto-N-biose degradation pathway in the probiotic bacterium Bifidobacterium longum.
