Cells were decorated with biotin through selective conjugation to ketone groups, and selectively killed in the presence of a ricin A chain-avidin conjugate. Ac4GalNAz treatment labeled the surface of healthy mouse corneas, leaving most cells viable, and bacteria preferentially associated with GalNAz-labeled regions. Insects protect themselves against bacterial infection by secreting a battery of antimicrobial peptides into the hemolymph. One leads directly to the final low-energy state and the other to the kinetic trap. Furthermore, the membrane-bound glycopolymers were internalized into early endosomes similarly to endogenous membrane components and were capable of specific interactions with protein receptors. The immobilization procedure itself was found not to activate primary T-cells, in contrast to previously reported antibody- and lectin-based methods. This work therefore extends the use of bioorthogonal labeling strategies to problems of clinical relevance. [85] Her father was of Italian descent. WebBio. Chem.

Here, we describe how pH-dependent partitioning drives asymmetric antimicrobial drug distribution in M. tuberculosis-infected macrophages. The polyvalent display of carbohydrate groups found on cell surface glycoprotein structures may contribute to the enhanced binding strength of selectin-mediated adhesion. O-Glycosylation affects relatively minor components of cell surfaces. This technique causes no discernible membrane or cell damage, and can deliver a discrete number of molecules to the cell's interior without the requirement of a carrier solvent. However, disruption of the dimer by mutagenesis did not affect either localization or substrate preference. The vast majority of H. ducreyi strains contain high levels of sialic acid (N-acetylneuraminic acid, NeuAc) in their LOS. Agre, P., Bertozzi, C., Bissell, M., Campbell, K. P., Cummings, R.

Systemic delivery of a targeted synthetic immunostimulant transforms the immune landscape for effective tumor regression. Atoms out of Blobs: CryoEM Takes the Nobel Prize in Chemistry. Four derivatives were experimentally verified in model reactions, and one, a 4-azidonaphthylfluorescein analogue, was further shown to label alkyne-functionalized proteins in vitro and glycoproteins on cells with excellent selectivity. The antibodies recognized cells that were fed the unnatural biosynthetic precursor, and were capable of directing complement-mediated lysis.Structural alteration of sialic acids replaces a tolerized self-antigen with an antigenic determinant. The new molecule class may be able to degrade some cardiovascular disease and cancer targets. A general method is described to sequester peptides containing azides from complex peptide mixtures, aimed at facilitating mass spectrometric analysis to study different aspects of proteome dynamics. These reactions possess extreme selectivity and biocompatibility, such that their participating reagents can form covalent bonds within richly functionalized biological systems--in some cases, living organisms.

ManLev was metabolized and incorporated into cell-surface glycoconjugates. WebProfessor Carolyn Bertozzi's research interests span the disciplines of chemistry and biology with an emphasis on studies of cell surface sugars important to human health and disease. Our method imparts N-glycopeptide mass envelopes with a pattern that is computationally distinguishable from background ions. She is currently a professor of Chemistry, Chemical and Systems Biology, and Radiology at Stanford University, and an Investigator at the Howard Hughes Medical Institute. These reactions can be used to tag glycans with imaging probes or epitope tags, thus enabling the visualization or enrichment of glycoconjugates. Thus, choice of enrichment strategy has profoundimplications on experimental outcomes. The unique chemical functionality of these analogs is exploited for selective attachment of singlet oxygen-generating fluorescent dyes via bioorthogonal 'click chemistry' ligations. High mannose glycans are not commonly presented on the surfaces of mammalian cells or in serum yet may play important roles in stem cell biology. Shieh, P., Siegrist, M. S., Cullen, A.

The prokaryotic homolog exhibits remarkable structural similarity to human FGE, including the position of catalytic cysteine residues. We treated worms with azidosugar variants of N-acetylglucosamine (GlcNAc), N-acetylgalactosamine (GalNAc), and N-acetylmannosamine (ManNAc), resulting in the metabolic labeling of their cell-surface glycans with azides. They also suggest increased P. aeruginosa adhesion to MyD88-/- and blotted corneas is not due to reduction in total surface glycosylation, and for tissue paper blotting is likely due to cell permeabilization.-Jolly, A. L., Agarwal, P., Metruccio, M. M. E., Spiciarich, D. R., Evans, D. J., Bertozzi, C. R., Fleiszig, S. M. J. Corneal surface glycosylation is modulated by IL-1R and Pseudomonas aeruginosa challenge but is insufficient for inhibiting bacterial binding.

In doing so, we examine prevailing notions about the number of modifications displayed on human proteins and how they combine to generate the protein diversity underlying health and disease. Finally, we demonstrate that the cell-surface Staudinger ligation is compatible with hydrazone formation from metabolically introduced ketones. Treatment of hESCs with Ac4-5SGlcNAc during induction limited protein O-GlcNAcylation and also caused a dramatic decrease in global levels of UDP-GlcNAc. Shon, D. J., Malaker, S. A., Pedram, K. n., Yang, E. n., Krishnan, V. n., Dorigo, O. n., Bertozzi, C. R. A Pragmatic Guide to Enrichment Strategies for Mass Spectrometry-Based Glycoproteomics. By contrast, most bacteria use trehalose solely as a general osmoprotectant or thermoprotectant. Glycans are central to many biological processes, but efforts to define their functions at the molecular level have been frustrated by a lack of suitable technologies. Fine-tuning of glycan biosynthetic pathways is further accomplished by specific associations among glycosyltransferases. Subsequently, the embryos were reacted with fluorophore conjugates by means of copper-free click chemistry, enabling the visualization of glycans in vivo at subcellular resolution during development. These results should facilitate mechanistic studies and the development of small molecule inhibitors of this enzyme family to ameliorate chronic inflammatory diseases. The availability of this new protocol greatly expands the applicability of the DNA-based attachment strategy for the generation of artificial tissues and the incorporation of living cells into device settings.

Direct visualization of proteins via the green fluorescent protein (GFP) and its congeners has revolutionized the field of protein dynamics. Glycoproteins are essential for cellular communication and are the most rapidly growing class of therapeutic agents. The mobility of CD45 increased markedly upon engagement of Fc receptors. The synthetic sugar decorated the cell surface with a unique ketone group that served as a foundation on which we built an adenovirus receptor by covalently binding biotin hydrazide to the ketone. The versatility of this technology was demonstrated by an example of selective drug delivery. The assay was validated by measuring K(M) values for PAPS and K(I) values for PAP, the product of sulfuryl transfer. [27][41], Bertozzi became a co-founder of Palleon Pharma of Waltham, Massachusetts, in 2015. Although the mechanisms of Golgi enzyme localisation are still under debate, the distribution of these enzymes among the Golgi cisternae can dictate the overall structures produced by the cell. Cell surface oligosaccharides can be engineered to display unusual functional groups for the selective chemical remodeling of cell surfaces. Mckl, L. n., Pedram, K. n., Roy, A.

The incorporation of noncanonical amino acids into recombinant proteins in Escherichia coli can be facilitated by the introduction of new aminoacyl-tRNA synthetase activity into the expression host. The lack of a defined consensus sequence for the ppGalNAcTs makes the prediction of mucin-type O-linked glycosylation difficult based on primary sequence alone. Cortez, F. d., Gebhart, D., Robinson, P. V., Seftel, D., Pourmandi, N., Owyoung, J., Bertozzi, C. R., Wilson, D. M., Maahs, D. M., Buckingham, B. Such structural alterations to cell surface glycans can be used to probe carbohydrate-dependent phenomena. Consequently, there is no obvious means to selectively monitor the behaviors of natural galectin ligands on live cell surfaces. Recurrent GBMs often exhibit mesenchymal, stem-like phenotypes that could explain their resistance to therapy. Site-selective protein modification based on covalent reactions of peptide tags and small molecules is a key capability for basic research as well as for the development of new therapeutic bioconjugates. Antigen presentation to Tcells in major histocompatibility complex class II (MHC class II) requires the conversion of early endo/phagosomes into lysosomes by a process called maturation. Thus, subtle structural differences in PSA resulting from the incorporation of SiaProp residues do not alter the antiadhesive properties of polysialylated NCAM. The active site residues of Rv3406 and AtsK are essentially superimposable, suggesting that the two sulfatases share the same catalytic mechanism. Agard, N. J., Baskin, J. M., Prescher, J.

Glycosylation is a prevalent, yet heterogeneous modification with a broad range of implications in molecular biology. In this report, we screened FGEs from M. tuberculosis and S. coelicolor against synthetic peptide libraries and identified new substrate sequences that diverge from the canonical motif. Protein glycosylation contributes to essential biological processes, but correlating glycan structure, underlying protein, and disease-relevant biosynthetic regulation is currently elusive. Specific glycocalyx compositions can also induce plasma membrane instabilities to generate more exotic undulating and pearled membrane structures and drive secretion of extracellular vesicles. Thus, BARAC is a promising reagent for in vivo imaging.
