Identification and biochemical characterization of a novel N-acetylglucosamine kinase in Saccharomyces cerevisiae.
Umekawa M., Nishikawa A., Isono N., Karita S.
N-acetylglucosamine (GlcNAc) is a key component of glycans such as glycoprotein and the cell wall. GlcNAc kinase is an enzyme that transfers a phosphate onto GlcNAc to generate GlcNAc-6-phosphate, which can be a precursor for glycan synthesis.

N-acetylglucosamine (GlcNAc) is a key component of glycans such as glycoprotein and the cell wall. GlcNAc kinase is an enzyme that transfers a phosphate onto GlcNAc to generate GlcNAc-6-phosphate, which can be a precursor for glycan synthesis. GlcNAc kinases have been found in a broad range of organisms, including pathogenic yeast, human and bacteria. However, this enzyme has never been discovered in Saccharomyces cerevisiae, a eukaryotic model. In this study, the first GlcNAc kinase from S. cerevisiae was identified and named Ngk1. The K<sub>m</sub> values of Ngk1 for GlcNAc and glucose were 0.11 mM and 71 mM, respectively, suggesting that Ngk1 possesses a high affinity for GlcNAc, unlike hexokinases. Ngk1 showed the GlcNAc phosphorylation activity with various nucleoside triphosphates, namely ATP, CTP, GTP, ITP, and UTP, as phosphoryl donors. Ngk1 is phylogenetically distant from known enzymes, as the amino acid sequence identity with others is only about 20% or less. The physiological role of Ngk1 in S. cerevisiae is also discussed. << Less
