An undecasaccharide mimetic was then readily generated by alkylation of this glycopeptide with an N-bromoacetamido trisaccharide. All mucin-associated [(35)S]sulfate was incorporated as GlcNAc-6-sulfate or Galbeta1-->4GlcNAc-6-sulfate. Previous structural analysis of the oligosaccharide chains on GlyCAM-1, an endothelial-derived ligand for L-selectin, revealed two novel structures: 6'-sulfo sialyl Lewis x and 6-sulfo sialyl Lewis x. This genetically encoded 'aldehyde tag' is no larger than a His(6) tag and can be exploited for numerous protein labeling applications. We previously established that mouse multipotent hematopoietic progenitors use ST8Sia IV to express polySia on their cell surfaces. Here, we discovered that osmotic stress stimulates a signaling network in Mycobacterium tuberculosis regulated by the eukaryotic-like receptor Ser/Thr protein kinase PknD. Sulfolipid-I (SL-I) is an abundant metabolite found in the cell wall of Mycobacterium tuberculosis that is comprised of a trehalose 2-sulfate core modified with four fatty acyl substituents.

The sulfite generated in this reaction is utilized in bacteria and plants for the eventual production of essential biomolecules such as cysteine and coenzyme A. Bioorthogonal chemical reactions are paving the way for new innovations in biology. Although their biochemical properties are similar in vitro, the enzymes have distinct glycoprotein substrate preferences in vivo. In the measurement, we add 50-nm-diameter superparamagnetic magnetite particles, coated with antibodies, to an aqueous sample containing L. monocytogenes. Complementation of the mutant strain restored PAT production, demonstrating that PapA3 is essential for the biosynthesis of this glycolipid in vivo. The installation of sulfate groups on the carbohydrate residues of glycoproteins, glycolipids, and glycosaminoglycans is a critical posttranslational modification that occurs in all higher eukaryotes.

C., Benson, J. The azido sugars are then covalently tagged with imaging probes or epitope tags, either ex vivo or in vivo, using an azide-specific reaction. The widespread role of sulfotransferases in modulating glycan function makes them prime targets for small-molecule modulators. Mycobacterium tuberculosis (M. tuberculosis) is an intracellular pathogen possessing a complex mixture of cell wall lipids that are thought to modulate the activities of host macrophages. Physiological blood-brain transport is impaired with age by a shift in transcytosis. At 60 hours after fertilization, we observed an increase in de novo glycan biosynthesis in the jaw region, pectoral fins, and olfactory organs. Synthetically lipidated recombinant green fluorescent protein (GFP) was shown to be stably anchored to the membrane, and its lateral fluidity was quantitatively characterized by direct fluorescence imaging in supported membranes. Shin, S., Chung, S., Sanii, B., Comolli, L. R., Bertozzi, C. R., De Yoreo, J. J. Mutants with defects in sulfate assimilation indicate that the fate of sulfur in M. tb is a critical survival determinant for the bacteria during infection and suggest novel targets for tuberculosis drug therapy.

Densely O-glycosylated mucin domains are found in a broad range of cell surface and secreted proteins, where they play key physiological roles. We used this strategy to construct a paracrine signaling network in isolated 3-dimensional microtissues. Glycosylation is a prevalent, yet heterogeneous modification with a broad range of implications in molecular biology. Bioinformatic analysis of the Mtb genome suggests the presence of a CysQ homologue encoded by the gene Rv2131c. In contrast, previous studies have shown that N-propanoyl sialic acid (SiaProp), generated from N-propanoylmannosamine, is readily accepted by polysialyltransferases and permits the extension of poly(SiaProp) on NCAM. Atoms out of Blobs: CryoEM Takes the Nobel Prize in Chemistry. Baker Family Director, Sarafan ChEM-H. Anne T. and Robert M. Bass Professor of Chemistry. Mycobacterium tuberculosis, the causative agent of tuberculosis, produces sulfated molecules that have eluded functional characterization for decades. Here we describe a strategy for exploiting trehalose metabolic pathways to label glycolipids in mycobacteria with azide-modified trehalose (TreAz) analogues. Within this bilayered structure, registry between lattices in two layers was disclosed, whereas the intrinsic symmetry in each layer was altered. We describe the application of click-EM in imaging metabolically tagged DNA, RNA and lipids in cultured cells and neurons and highlight its use in tracking peptidoglycan synthesis in the Gram-positive bacterium Listeria monocytogenes. Cell surfaces are endowed with biological functionality designed to mediate extracellular communication. In this study we probed the importance of the stem region with respect to substrate preference, localization, and oligomerization. Instead, MECA-79 bound preferentially to 6-sulfolactose. Using these probes, chemoselective imaging of either H(2)O(2) or caspase 8 activity was performed in vitro and in vivo. UDP-GlcNAc 2-epimerase and GlcNAc 2-epimerase are two enzymes capable of generating ManNAc from UDP-GlcNAc and GlcNAc, respectively. Here, we develop a "bump-hole" chemical reporter system for studying GalNAc-T activity in vitro. A., Bertozzi, C. R. Synthetic Trehalose Glycolipids Confer Desiccation Resistance to Supported Lipid Monolayers. We fed cells an unnatural monosaccharide, a modified mannosamine that replaced the acetyl group with a levulinate group (ManLev). The ESI-MS assay is used to determine NodST kinetic parameters, including K(M), V(max), and K(i) (for PAP). Metabolic conversion of ManNAz to N-azidoacetylsialic acid (SiaNAz) within membrane-bound and secreted glycoproteins was quantified in a variety of cell types. Andres, L. M., Blong, I. W., Evans, A.

Some of these techniques remove obstacles to glycoprotein synthesis by installing nonnative linkages and other modifications for facilitated assembly. CNTs coated with these mucin mimic polymers have two novel properties: they can bind to carbohydrate receptors, providing a means for biomimetic interactions with cell surfaces, and, importantly, they are rendered nontoxic to cells. Shes been out since the late 1980s, when being a lesbian could have jeopardized her career. Her research group profiles changes in cell surface glycosylation associated with cancer, inflammation and bacterial infection, and uses this information to develop new Her recent efforts include synthesis of chemical tools to study cell surface sugars called glycans and how they affect diseases Biography. 28 Feb 2023 13:00:30 Insects protect themselves against bacterial infection by secreting a battery of antimicrobial peptides into the hemolymph. [6] In 1999, while working with HHMI and at Berkeley, she founded the field of bioorthogonal chemistry and coined the term in 2003. On the basis of these results, we propose possible pathways for 6-sulfo sialyl Lewis x biosynthesis and suggest that sulfation may be an early committed step. A mineralization technique was developed that exposes carboxylate groups on the surface of cross-linked pHEMA, promoting high-affinity nucleation and growth of calcium phosphate on the surface, along with extensive calcification of the hydrogel interior. Surprisingly, corneas from MyD88-/- mice displayed similar GalNAz labeling to wild-type corneas, but labeling was reduced and patchy on IL-1 receptor (IL-1R)-knockout mouse corneas (P < 0.05, ANOVA). Metabolic labeling with GalNAz followed by Staudinger ligation provides a means for proteomic analysis of this posttranslational modification and for identifying O-linked glycoprotein fingerprints associated with disease. Haemophilus ducreyi is a Gram-negative bacterium that causes chancroid, a sexually transmitted disease. View details for Web of Science ID 000305107800004, View details for PubMedCentralID PMC3374418. Further, enzymatically simplified N-glycans are preserved on peptides. Their large size and extensive glycosylation makes the synthesis of these biopolymers impractical. Antibody-drug conjugates (ADCs) selectively deliver chemotherapeutic agents to target cells and are important cancer therapeutics. This protocol outlines both the generation and the analysis of proteins aldehyde-tagged at their termini and the methods for chemical conjugation to the formylglycine.

GlyCAM-1 was metabolically labeled in lymph node organ culture with 35SO4 and a panel of tritiated carbohydrate precursors. Wei, W., Riley, N. M., Lyu, X., Bertozzi, C. R., Long, J. Even though we have only demonstrated its use in visualizing glycans, it can be envisioned that this probe could also be used for bioluminescence imaging of any azide-containing biomolecule, such as proteins and lipids, since azides have been previously incorporated into these molecules. Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, is a highly evolved human pathogen characterized by its formidable cell wall. Collectively, these chemical approaches are contributing great insight into the myriad biological functions of oligosaccharides. Synthetic mimics of the complex assemblies found on cell surfaces can modulate cellular interactions and are under development as therapeutic agents. This heterogeneity precludes enrichment strategies that can be universally beneficial for all glycan classes. Here we introduce the quadricyclane ligation, a new bioorthogonal reaction between the highly strained hydrocarbon quadricyclane and Ni bis(dithiolene) reagents. OliLux Biosciences develops new methods for tuberculosis detection. Three piperidine-melamine glycodendrimers were synthesized via a chemoenzymatic route and attached to human growth hormone and the Fc region of human IgG. Here we describe an efficient dot-blot assay for high-throughput screening of two enzymes, heparan sulfate N-deacetylase/N-sulfotransferase (NDST-1) and high-endothelial cell GlcNAc-6-sulfotransferase (HEC-GlcNAc-6-ST).

This approach can highlight changes in physiology or environment and may be more informative than steady-state analyses. Illumination of dye-labeled structures generates singlet oxygen to locally catalyze the polymerization of diaminobenzidine into an osmiophilic reaction product that is readily imaged by EM. The advantage of this ELISA over previous assays is that a macromolecular physiological ligand is employed, rather than a fortuitous or simplified carbohydrate ligand. The concepts outlined herein lay a foundation for future development of peptide tags in the context of site-selective modification of lysine residues within engineered microenvironments. Surprisingly, Gal-1's effects on mammary patterning were independent of its glycan-binding ability and instead required localization within the nuclei of mammary epithelia. The capability of the nanoinjector was demonstrated by injection of protein-coated quantum dots into live human cells. Glycocalyx Engineering with a Recycling Glycopolymer that Increases Cell Survival In Vivo. The sulfate esters on these structures are thought to be essential for high-affinity binding to L-selectin. We used this method to regulate production of sialyl Lewis x by alpha1,3-fucosyltransferase VII in living cells. These technological hurdles are especially troublesome in detecting antibodies that bind nonlinear or conformational epitopes, such as anti-insulin antibodies in type 1 diabetes patients and anti-thyroglobulin antibodies associated with thyroid cancers.

Humans do not possess a homologous metabolic pathway, and thus, these enzymes represent attractive targets for therapeutic intervention. Drawing on these results, we analyzed the relationship between alkyne bond angles, which we determined using X-ray crystallography, and reactivity, quantified by experimental second-order rate constants, for a range of cyclooctynes. Numerous factors that influence cell-surface carbohydrate composition remain to be elucidated. These modified proteins integrated into the plasma membranes of a variety of mammalian cells and were internalized and directed to recycling endosomes similarly to GFP bearing a native GPI anchor.

The most widely used CID, the natural product rapamycin and its relatives, is immunosuppressive due to interactions with endogenous targets and thus has limited utility in vivo. These efforts epitomize the emerging field of 'synthetic glycobiology'. For N-glycopeptides, HCD and sceHCD generate similar numbers of identifications, although sceHCD generally provides higher quality spectra. Several anti-tuberculosis drugs target the biogenesis of this complex envelope, but their efficacy is declining due to resistance. The complex and diverse structures of GPI anchors suggest a rich spectrum of biological functions, but few have been confirmed experimentally because of the lack of appropriate techniques that allow for structural perturbation in a cellular context. Conversely, ETD-based methods, especially EThcD, are indispensable for site-specific analyses of O-glycopeptides. The leukocyte adhesion molecule L-selection participates in the initial attachment of blood-borne lymphocytes to high endothelial venules (HEVs) during lymphocyte homing to secondary lymphoid organs, and contributes to leukocyte adhesion and extravasation in HEV-like vessels at sites of chronic inflammation.
