Authors. Qiushi Chen, Juliane S. Muller, Poh-Choo Pang, Steve H. Laval, Stuart M. Haslam, Hanns Lochmüller and Anne Dell. Journal. Biomolecules, volume 2015, issue 5, pages 2758-2781 Publication date. October 2015. Abstract. Glutamine-fructose-6-phosphate transaminase 1 (GFPT1) is the first enzyme of the hexosamine biosynthetic pathway. It transfers an amino group from glutamine to fructose-6-phosphate to yield glucosamine-6-phosphate, thus providing the precursor for uridine diphosphate N-acetylglucosamine (UDP-GlcNAc) synthesis. UDP-GlcNAc is an essential substrate for all mammalian glycosylation biosynthetic pathways and N-glycan branching is especially sensitive to alterations in the concentration of this sugar nucleotide. It has been reported that GFPT1 mutations lead to a distinct sub-class of congenital myasthenic syndromes (CMS) termed limb-girdle CMS with tubular aggregates. CMS are hereditary neuromuscular transmission disorders in which neuromuscular junctions are impaired. To ...

Although many recent developments in glycomics focus on structural and functional analysis of surface-displayed sugars, the biosynthetic machinery that builds these complex molecules also greatly interests the glycobiologist. We briefly discuss carbohydrate biosynthesis here, both to acknowledge the heroic researchers who laid an impressive foundation without benefit of large-scale technologies and to illustrate the need for high-throughput strategies to accelerate progress. We use the term glycosylation machinery to describe biochemical pathways that convert monosaccharides (for example, dietary glucosamine) into nine different high-energy sugar-nucleotide building blocks (for example, UDP-N-acetylglucosamine (UDP-GlcNAc)) and assemble them into the complex oligosaccharides found on proteins and lipids (Figure 1). Basic components of this metabolic factory were discovered in a painstakingly slow, one-at-a-time process over many decades (for a detailed perspective, see the fascinating ...

Glycosylation is essential for growth factor signaling through N-glycosylation of ligands and receptors and the biosynthesis of proteoglycans as co-receptors. Here, we show that protein O-GlcNAcylation is crucial for fibroblast growth factor (FGF) signaling in Drosophila. We found that nesthocker (nst) encodes a phosphoacetylglucosamine mutase and that nst mutant embryos exhibited low amounts of intracellular uridine 5′-diphosphate-N-acetylglucosamine (UDP-GlcNAc), which disrupted protein O-GlcNAcylation. Nst was required for mitogen-activated protein kinase (MAPK) signaling downstream of FGF but not MAPK signaling activated by epidermal growth factor. nst was dispensable for the function of the FGF ligands and the FGF receptors extracellular domain but was essential in the signal-receiving cells downstream of the FGF receptor. We identified the adaptor protein Downstream of FGF receptor (Dof), which interacts with the FGF receptor, as the relevant target for O-GlcNAcylation in the FGF ...

1. The binding of substrates and effectors to glucosamine synthetase (l-glutamine-d-fructose 6-phosphate aminotransferase, EC 2.6.1.16) was studied by using the ligand to alter the denaturation rate of the enzyme. The free enzyme bound fructose 6-phosphate, glucose 6-phosphate and UDP-N-acetylglucosamine, but not glutamine, AMP or UTP. Glucose 6-phosphate and AMP increased the binding of UDP-N-acetylglucosamine whereas UTP decreased the interaction between the enzyme and the feedback inhibitor. UDP-N-acetylglucosamine induced a glutamine-binding site on the enzyme. 2. Selective thermal or chemical denaturation revealed that the UDP-N-acetylglucosamine-binding site was not located at the catalytic site. The UTP site could not be distinguished from that for the nucleotide sugar. The AMP- and glucose 6-phosphate-binding sites were distinct from the catalytic and feedback-inhibitor-binding sites. 3. The specificity of the glutamine-binding site was investigated by using a series of potential ...

Bifunctional protein GlmU; Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP- GlcNAc). The C-terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N-acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5- monophosphate (from uridine 5-triphosphate), a reaction catalyzed by the N-terminal ...

Some oomycetes species are severe pathogens of fish or crops. As such, they are responsible for important losses in the aquaculture industry as well as in agriculture. Saprolegnia parasitica is a major concern in aquaculture as there is currently no method available for controlling the diseases caused by this microorganism. The cell wall is an extracellular matrix composed essentially of polysaccharides, whose integrity is required for oomycete viability. Thus, the enzymes involved in the biosynthesis of cell wall components, such as cellulose and chitin synthases, represent ideal targets for disease control. However, the biochemical properties of these enzymes are poorly understood, which limits our capacity to develop specific inhibitors that can be used for blocking the growth of pathogenic oomycetes.. In our work, we have used Saprolegnia monoica as a model species for oomycetes to characterize two types of domains that occur specifically in oomycete carbohydrate synthases: the Pleckstrin ...

This gene is a member of the glycosyltransferase 31 gene family. Members of this gene family, which also includes the MFNG (GeneID: 4242) and RFNG (GeneID: 5986) genes, encode evolutionarily conserved glycosyltransferases that act in the Notch signaling pathway to define boundaries during embryonic development. While their genomic structure is distinct from other glycosyltransferases, these proteins have a fucose-specific beta-1,3-N-acetylglucosaminyltransferase activity that leads to elongation of O-linked fucose residues on Notch, which alters Notch signaling. The protein encoded by this gene is predicted to be a single-pass type II Golgi membrane protein but it may also be secreted and proteolytically processed like the related proteins in mouse and Drosophila (PMID: 9187150). Mutations in this gene have been associated with autosomal recessive spondylocostal dysostosis 3. [provided by RefSeq, May 2018 ...

Author(s): Ngo, Alice; Fong, Kai T; Cox, Daniel L; Chen, Xi; Fisher, Andrew J | Abstract: Uridine 5-diphosphate-N-acetylglucosamine (UDP-GlcNAc) acyltransferase (LpxA) catalyzes a reversible reaction for adding an O-acyl group to the GlcNAc in UDP-GlcNAc in the first step of lipid A biosynthesis. Lipid A constitutes a major component of lipopolysaccharides, also referred to as endotoxins, which form the outer monolayer of the outer membrane of Gram-negative bacteria. Ligand-free and UDP-GlcNAc-bound crystal structures of LpxA from Bacteroides fragilis NCTC 9343, the most common pathogenic bacteria found in abdominal abscesses, have been determined and are presented here. The enzyme crystallizes in a cubic space group, with the crystallographic threefold axis generating the biological functional homotrimer and with each monomer forming a nine-rung left-handed β-helical (LβH) fold in the N-terminus followed by an α-helical motif in the C-terminus. The structure is highly similar to LpxA from other

Abstract: The biosynthetic pathway of peptidoglycan is essential for Mycobacterium tuberculosis. We report here the acetyltransferase substrate specificity and catalytic mechanism of the bifunctional N-acetyltransferase/uridyltransferase from M. tuberculosis (GlmU). This enzyme is responsible for the final two steps of the synthesis of UDP-N-acetylglucosamine, which is an essential precursor of peptidoglycan, from glucosamine-1-phosphate, acetyl coenzyme A and uridine-5-triphosphate. GlmU utilizes requires ternary complex formation to transfer an acetyl from acetyl coenzyme A to glucosamine-1-phosphate to form N-acetylglucosmaine-1-phosphate. Steady-state kinetic studies and equilibrium binding experiments indicate that GlmU follows a steady-state ordered kinetic mechanism, with acetyl coenzyme A binding first, which triggers a conformational change on GlmU, followed by glucosamine-1-phosphate binding. Coenzyme A is the last product to dissociate. Chemistry is partially rate-limiting as ...

The formation of heparin-precursor polysaccharide (N-acetylheparosan) was studied with a mouse mastocytoma microsomal fraction. Incubation of this fraction with UDP-[3H]GlcA and UDP-GlcNAc yielded labelled macromolecules that could be depolymerized, apparently to single polysaccharide chains, by alkali treatment, and thus were assumed to be proteoglycans. Label from UDP-[3H]GlcA (approx. 3 microM) is transiently incorporated into microsomal polysaccharide even in the absence of added UDP-GlcNAc, probably owing to the presence of endogenous sugar nucleotide. When the concentration of exogenous UDP-GlcNAc was increased to 25 microM the rate of incorporation of 3H increased and proteoglycans carrying polysaccharide chains with an Mr of approx. 110,000 were produced. Increasing the UDP-GlcNAc concentration to 5 mM led to an approx. 4-fold decrease in the rate of 3H incorporation and a decrease in the Mr of the resulting polysaccharide chains to approx. 6000 (predominant component). When both ...

This gene encodes a glycosyltransferase that catalyzes the addition of a single N-acetylglucosamine in O-glycosidic linkage to serine or threonine residues. Since both phosphorylation and glycosylation compete for similar serine or threonine residues, the two processes may compete for sites, or they may alter the substrate specificity of nearby sites by steric or electrostatic effects. The protein contains multiple tetratricopeptide repeats that are required for optimal recognition of substrates. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Oct 2009 ...

The solute carrier family Slc35 consists of at least 17 proteins that act as nucleotide sugar transporters localized to the Golgi apparatus and endoplasmic reticulum. The role of the ER-resident Slc family member Slc35D1 is to transport both UDP-glucuronic acid and UDP-N-acetylgalactosamine. These molecules can serve as substrates for chondroitin sulfate biosynthesis and mice lacking the Slc35D1 gene developed a lethal form of skeletal dysplasia with severe shortening of limbs and facial structures. Examination of epiphyseal cartilage in these mice revealed a decreased proliferating zone with round chrondrocytes, scarce matrices, and reduced proteoglycan aggregates. Loss of function mutations in human Slc35D1 cause Schneckenbecken dysplasia, a severe skeletal dysplasia. This antibody is predicted to not cross-react with the highly homologous Slc35D2. ...
