During the search for inhibitors of N-acetylneuraminic acid biosynthesis, it was shown that 3-O-methyl-N-acetylglucosamine competitively inhibits the N-acetylglucosamine kinase of rat liver in vitro with a Ki value of 17 microM. N-Acetylmannosamine kinase is inhibited non-competitively with a Ki value
Glucokinase, an enzyme that catalyzes the phosphorylation of glucose, constitutes the key regulatory step in glucose metabolism in pancreatic islets and liver. We found that 3-O-methyl-N-acetyl-D-glucosamine (3-O-methyl-GlcNAc) potently inhibits glucose phosphorylation by N-acetylglucosamine kinase whereas glucokinase is not at all

Equilibrium dialysis studies on the binding of the Dolichos biflorus lectin with [14C]methyl alpha-D-GalNAc showed that the lectin has two combining sites/molecule and an intrinsic association constant at 3 degrees C of 4.2 X 10(3) liters mol-1. Binding studies on

A novel phosphonoglycosphingolipid named SGL-I containing 3 mol of 2-aminoethylphosphonate residues was isolated from the skin of a sea gastropod, Aplysia kurodai. The saccharide moiety of the glycolipid was characterized as 4-O-methyl-GlcNAc alpha 1----4GalNAc alpha-1----3 [6'-O-(2-aminoethylphosphonyl)Gal alpha 1----2] (2-aminoethylphosphonyl----6)Gal beta
