A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6. In a Article,once mentioned of 14215-68-0, name: N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide
The biantennary oligosaccharide analogue beta-D-GlcpNAc-(1 ? 2)-alpha-D-Manp-(1 ? 3)[beta-D-GlcpNAc-(1 ? 2)-alpha-D-Manp-(1 ? 6)]-beta-D-Manp-O(CH2)8COOMe (3) is a potential substrate for N-acetylglucosaminyltransferases (GlcNAcTs) III-V which are present in mammalian cells. The di-O-methylated analogue of 3, beta-D-GlcpNAc-(1 ? 2)-[4-O-methyl-alpha-D-Manp]-(1 ? 3)-[beta-D-GlcpNAc-(1 ? 2)-[6-O-methyl-alpha-D-Manp]-(1 ? 6)]-beta-D-Manp-O(CH2)8COOMe (5), was prepared by a block synthesis approach involving sequential addition of two O-methylated disaccharide donors to a protected central beta-D-Man residue. The OH groups acted on by GlcNAcT-IV and -V are protected from glycosylation in 5 since they are present as their methyl ethers. Pentasaccharide 5 was found to be an excellent substrate for GlcNAcT-III (EC 2.4.1.144) from rat kidney with K(m) = 0.15 mM. The product formed by incubation of 5 with a rat kidney extract, in the presence of UDP-GlcNAc, was isolated, structurally characterized by NMR spectroscopy and confirmed to be the expected di-O-methyl hexasaccharide where a beta-D-GlcpNAc residue had been added to OH-4 of the central beta-D-Manp unit. The biantennary oligosaccharide analogue beta-D-Glc pNAc-(1?2)-alpha-D-Man p-(1?3)-[beta-D-Glc pNAc-(1?2)-alpha-D-Man p-(1?6)]-beta-D-Man p-O(CH2)8COOMe (3) is a potential substrate for N-acetylglucosaminyltransferases (GlcNAcTs) III-V which are present in mammalian cells. The di-O-methylated analogue of 3, beta-D-Glc pNAc-(1?2)-[4-O-methyl-alpha-D-Man p]-(1?3)-[beta-D-Glc pNAc-(1?2)-[6-O-methyl-alpha-D-Man p]-(1?6)]-beta-D-Man p-O-(CH2)8COOMe (5), was prepared by a block synthesis approach involving sequential addition of two O-methylated disaccharide donors to a protected central beta-D-Man residue. The OH groups acted on by GlcNAcT-IV and -V are protected from glycosylation in 5 since they are present as their methyl ethers. Pentasaccharide 5 was found to be an excellent substrate for GlcNAcT-III (EC 2.4.1.144) from rat kidney with Km = 0.15 mM.
