The absence of activity on the trisaccharide Gal beta 1-->6Gal alpha-R indicates a requirement for a substrate with a terminal GlcNAc residue, suggesting that sulfation precedes further biosynthetic assembly of L-selection ligands. Mycobacterium tuberculosis, the causative agent of tuberculosis, produces unique sulfated metabolites associated with virulence. This story was updated on Wednesday, Oct. 6, at 1:23 p.m. PDT. The use of bioorthogonal chemistry has contributed to advances in different areas of biomedical research, including cancer drug development and molecular imaging. Kumar, P., Schelle, M. W., Jain, M., Lin, F. L., Petzold, C. J., Leavell, M. D., Leary, J. We find that monomers with an extended conformation first form a mobile adsorbed phase, from which they condense into amorphous clusters. We describe a method for modifying proteins site-specifically using a chemoenzymatic bioconjugation approach. Shao, Z., Flynn, R. A., Crowe, J.

Through a small molecule screen, we identified a cell-active NGLY1 inhibitor that disrupts the processing and function of Nrf1. This assembly inhibits L-, E-, and P-selectin binding to GlyCAM-1, a physiological ligand better than sLe(x)-like liposomes without additional anionic charge. A correlation between hypersialylation and immunoprotection has been observed, but few hypotheses have provided a mechanistic understanding of this immunosuppressive phenomenon. Azido sugars are fed to cells and integrated by the glycan biosynthetic machinery into various glycoconjugates. Bertozzi, C. R., Fukuda, S., ROSEN, S. D. CRACKING THE CARBOHYDRATE CODE FOR SELECTIN RECOGNITION, IDENTIFICATION OF THE SULFATED MONOSACCHARIDES OF GLYCAM-1, AN ENDOTHELIAL-DERIVED LIGAND FOR L-SELECTIN. Research on the human pathogen Mycobacterium tuberculosis (Mtb) would benefit from novel tools for regulated gene expression. Regrettably, conventional biochemical and genetic methods often fall short for the study of glycans, because their structures are often not precisely defined at the genetic level. Through comparative analysis of screens with ADCs bearing different linkers, we show that a subset of late endolysosomal regulators selectively influence toxicity of noncleavable linker ADCs.

She is a member of the National Academy of Sciences (2005), the Institute of Medicine (2011), and the National Academy of Inventors (2013). The quadricyclane (QC) ligation is a bioorthogonal reaction between a quadricyclane moiety and a nickel bis(dithiolene) derivative. Mtb capture was calculated per exhaled air volume sampled and bioaerosol volume for RASC-1 (n = 35) and for RASC-2 (n = 21). She coined the term bioorthogonal chemistry to Most clinically approved biomarkers of cancer are glycoproteins, and those residing on the cell surface are of particular interest in biotherapeutics. Perrine, C. L., Ganguli, A., Wu, P., Bertozzi, C. R., Fritz, T. A., Raman, J., Tabak, L. A., Gerken, T. A. Polysialic acid governs T-cell development by regulating progenitor access to the thymus. Herein, we designed and synthesized the first chemically defined ligands for dectin-1 and dectin-2. O-linked -N-acetylglucosamine (O-GlcNAc) is a reversible posttranslational modification found on hundreds of nuclear and cytoplasmic proteins in higher eukaryotes. This enzyme transfers sialic acid residues from the host's sialylglycoconjugates to the parasite's galactosylglycoconjugates. Nevertheless, CD45 remained to be the main acceptor. Her research group profiles changes in cell surface glycosylation associated with cancer, inflammation and bacterial infection, and uses this information to develop new We previously described a chemical method to image glycans during zebrafish larval development; however, we were unable to detect glycans during the first 24 hours of embryogenesis, a very dynamic period in development. Mockl, L., Pedram, K., Roy, A., Krishnan, V., Gustavsson, A., Dorigo, O., Bertozzi, C., Moerner, W. Enzyme toolkit for selective enrichment and analysis of mucin-domain glycoproteins. Tyrosylprotein sulfotransferases (TPSTs) catalyze the sulfation of tyrosine residues within secreted and membrane-bound proteins. The active cuprous FGE complex was interrogated directly by X-ray absorption spectroscopy. These stratergies for cell surface 'glycoform remodeling' promise to facilitate the investigation of carbohydrate mediated cell-cell interactions. Thus, this metabolic gene of an intracellular pathogen could have a secondary role in protection against the host immune response. We investigated how the major phosphatase CD45 is excluded from contact sites, using single-molecule tracking. DIFBO was so reactive that it spontaneously trimerized to form two asymmetric products that we characterized by X-ray crystallography. The biological study of O-linked glycosylation is particularly problematic, as chemical tools to control this modification are lacking. WebCarolyn Ruth Bertozzi (born October 10, 1966) is an American chemist and Nobel laureate, known for her wide-ranging work spanning both chemistry and biology. These modified GFPs were incorporated in supported lipid bilayers, and their mobilities were analyzed using fluorescence correlation spectroscopy.

Finally, we showed that BNNTs can deliver DNA oligomers to the interior of cells with no apparent toxicity. Spreading of a mycobacterial cell surface lipid into host epithelial membranes promotes infectivity. The data from these experiments suggest that the GPI anchor is more than a simple membrane-anchoring device; it also may prevent transient interactions between the attached protein and the underlying lipid bilayer, thereby permitting rapid diffusion in the bilayer. [27][44], She co-founded Grace Science Foundation in 2018. The ketone group on the cell surface can then be covalently ligated under physiological conditions with molecules carrying a complementary reactive functional group such as the hydrazide. However, their weak binding interactions do not correlate with the high-affinity binding interactions witnessed in vivo. Highlights of recent progress include an extension of the list of instances of selectin participation in inflammatory diseases, further definition of selectin carbohydrate specificities, and identification of their carbohydrate-based ligands.

[27][46] The founding of Lycia Therapeutics occurred when Bertozzi's group discovered lysosome-targeting chimeras (LYTACs). This phenotype probably reflects a decreased capacity of the ST8Sia IV(-/-) progenitors to escape from the bone marrow niche. Here, we demonstrate that, relative to wild-type controls, ST8Sia IV(-/-) mice have a 30% reduction in total thymocytes and a concomitant deficiency in the earliest thymocyte precursors. We describe a metabolism-based approach to the selection of mutants in glycoconjugate biosynthesis that provides insight into regulatory mechanisms for oligosaccharide expression and metabolic flux. Carolyn Bertozzi is a chemist who has made important contributions to understanding how cells interact. These results establish the foundation for further development of BPDA-based colorimetric sensors. This work therefore extends the use of bioorthogonal labeling strategies to problems of clinical relevance. Living organisms produce hydrogen peroxide (H(2)O(2)) to kill invading pathogens and for cellular signaling, but aberrant generation of this reactive oxygen species is a hallmark of oxidative stress and inflammation in aging, injury, and disease. Cyclopropanation of the mycobacterial cell wall glycolipid trehalose dimycolate is both required and sufficient to induce robust host angiogenesis. In eukaryotic sulfatases, an active site cysteine residue is oxidized to the aldehyde-containing C(alpha)-formylglycine residue by the formylglycine-generating enzyme (FGE). This purpose of this mini review is to familiarizereaders with the tools currently available for the synthesis of mucin-typeglycoproteins.

These results establish cell-surface glycoproteomics as an effective technique for discovery of cancer biomarkers. The L-selection ligands on lymph mode HEVs are mucin-like glycoproteins adorned with the unusual sulfated carbohydrate epitope, 6-sulfo sialyl Lewis x. Sulfation of this epitope on the N-acetylglucosamine (GlcNAc) residue confers high-avidity L-selection binding, and is thought to be restricted in the vasculature to sites of sustained lymphocyte recruitment. A metabolic labeling approach for glycoproteomic analysis reveals altered glycoprotein expression upon GALNT3 knockdown in ovarian cancer cells. These observations suggest crosstalk between autophagy and phagocytosis that may be relevant to the innate immune response of macrophages. 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.

Specific labeling of biomolecules with biochemical and biophysical probes is a central element of proteomics research. Among her many honours are the Lemelson-MIT Prize (2010), the Arthur C. Cope Award of the American Chemical Society (2017), and the Wolf Prize in Chemistry (2022). Chemical tools have proven indispensable for studies in glycobiology. Mucin-selective proteolysis, as exemplified by StcE, is therefore a powerful tool for the study of mucin domain structure and function. The unique labeling strategy of BCG by CDG-Tre provides a versatile tool for tracking Mtb in both pre- and post-phagocytosis and elucidating fundamental physiological and pathological processes related to the mycomembrane. Here, we report the use of azido-modified unnatural sialic acid to identify those molecules that act as cell surface acceptors of the sialyl residue in the trans-sialidase-catalyzed reaction, which might then be involved in the immune alterations induced.

Once introduced into target biomolecules, either metabolically or through chemical modification, the azide can be tagged with probes using one of three highly selective reactions: the Staudinger ligation, the Cu(I)-catalyzed azide-alkyne cycloaddition, or the strain-promoted [3 + 2] cycloaddition. However, when activity of the vacuolar H+-ATPase was also inhibited, disulfide reduction decreased SHGFP-MUC5AC/CK t((1/2)) while diminishing its intraluminal concentration. Mycobacterium tuberculosis ( Mtb) produces a number of sulfur-containing metabolites that contribute to its pathogenesis and ability to survive in the host. and Shu Wang and Kim, {Hyun Jae} and Meyer, {Gerald J.} Redundancy of related family members and embryonic lethality both complicate genetic methods for deconvoluting functions of glycosyltransferases.
