The tremendous selectivity of the transformation should permit its execution within a cell's interior, offering new possibilities for probing intracellular interactions. Notably, the reaction of azides with terminal alkynes can be accelerated dramatically by copper catalysis (this highly popular Cu-catalyzed azide-alkyne cycloaddition (CuAAC) is a quintessential "click" reaction). Our approach capitalizes on two features shared by these enzymes: their requirement of Golgi localization for activity on cellular substrates and the modularity of their catalytic and localization domains. We fed cells an unnatural monosaccharide, a modified mannosamine that replaced the acetyl group with a levulinate group (ManLev). SL-1 consists of a trehalose-2-sulfate (T2S) disaccharide elaborated with four lipids. Finally, we obtained structural and computational data that revealed the relationship between the conformation of BARAC's central lactam and compound reactivity. The ability to label mucin-type O-linked glycoproteins with chemical tags should facilitate their identification by proteomic strategies. Both biochemical and structural data indicate the presence of an oxidized cysteine modification in the active site that may be relevant to catalysis. Antibodies bind to and agglutinate synthetic antigen-DNA conjugates, enabling ligation of the DNA strands and subsequent quantification by qPCR. This reaction has a second-order rate constant of 0.25 M(-1) s(-1), on par with fast bioorthogonal reactions of azides, and proceeds readily in aqueous environments. Protocol for cell type-specific labeling, enrichment, and proteomic profiling of plasma proteins in mice. We employed the recently introduced aldehyde tag method to obtain a recombinant protein with the aldehyde-bearing formylglycine residue at a specific site. In the 1990s, Dr. Bertozzi was studying glycans, carbohydrates that sit on the surfaces of proteins and cells, the functions of which were not wholly understood. Metabolic and bioorthogonal labeling methods have previously enabled the enrichment and identification of sialoglycoproteins from cultured cells and model organisms. Senaratne, R. H., Mougous, J.

Application of the IsoTaG platform to 15 cell lines metabolically labeled with Ac4GalNAz or Ac4ManNAz revealed 1375 N- and 2159 O-glycopeptides, variously modified with 74 discrete glycan structures. This complex could be stored as a lyophilized powder and then dissociated in organic solvents to produce free DIFBO for in situ kinetic and spectroscopic analysis. Glycosyltransferases responsible for synthesis of cell surface oligosaccharides are therefore essential administrators of cellular communication. The location of the surface-anchored TS resulted too far off as to be capable to sialylate mucins, a role played by the shed TS instead.

However, a detailed structural analysis of S881 has remained elusive. We use a novel fractionation procedure to demonstrate that SL-1 is present on the cell surface, whereas SL(1278) is found exclusively in more internal layers. Carolyn Bertozzi biography.

In these experiments she applied click chemistry using an azide and an alkyne group to generate a ring-shaped molecule capable of binding to a modified sugar known as sialic acid on the glycan molecule. Using these probes, we studied the mobilities of labeled glycolipids by time-lapse microscopy and fluorescence recovery after photobleaching experiments and found that mycomembrane fluidity varies widely across species and correlates with mycolic acid structure. Single Jurkat cells exhibited an extracellular acidification rate of 11 milli-pH min(-1), while primary T cells exhibited only 2 milli-pH min(-1). Yet, a mechanistic understanding of how O-GlcNAc functions in T cell activation remains elusive, partly because of the difficulties in mapping and quantifying O-GlcNAc sites. Collectively, these results provide evidence that polySia is involved in hematopoietic development. Mutations in the colony stimulating factor 3 receptor (CSF3R) have been identified in the vast majority of patients with chronic neutrophilic leukemia and are present in other kinds of leukemia, such as AML.

LYTACs that engage the asialoglycoprotein receptor for targeted protein degradation. Physical and Materials Sciences, Energy and the Environment, Shadow Program (for High School students). Lastly, we show that sialic acid depletion enhances ADC lysosomal delivery and killing in diverse cancer cell types, including with FDA (US Food and Drug Administration)-approved trastuzumab emtansine (T-DM1) in Her2-positive breast cancer cells. In this work, we undertook a mechanistic study of the Staudinger ligation with a focus on factors that affect reaction kinetics and on the identification of intermediates. Accurate mass measurements indicated an oxidation state of +2 for the 4Fe-4S cluster, with no disulfide bond in the holoenzyme. Upon exposure to mycobacterial cell wall lipids, 166 macrophage proteins showed differential expression. [16], Bertozzi completed her Ph.D. in chemistry at University of California, Berkeley in 1993 with Mark Bednarski, working on the chemical synthesis of oligosaccharide analogs. Additionally, we have utilized computational methods to understand the unique properties of these fully conjugated macrocycles. Modification of the terminal arabinan residues of this lipoglycan with mannose caps in M. tuberculosis or with phosphoinositol caps in Mycobacterium smegmatis results in distinct host immune responses.

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. Our editors will review what youve submitted and determine whether to revise the article. Bhat, R., Belardi, B., Mori, H., Kuo, P., Tam, A., Hines, W. C., Quynh-Thu Le, Q. T., Bertozzi, C. R., Bissell, M. J. Although theoretical predictions suggest that proteins follow these pathways as a result of fluctuations that create unstable dense-liquid states, microscopic studies indicate these states are long-lived. Specifically, 2,6-sialylation of terminal LacNAc residues in the end buds masked Gal-1 ligands, thereby liberating the protein for nuclear translocation. This system enables the production of glycoproteins that are functionalized for specific chemical modifications at their glycosylation sites. Here we report that a bulky glycocalyx promotes the expansion of disseminated tumor cells in vivo by fostering integrin adhesion assembly to permit G1 cell cycle progression. An inhibitor of the UDP-GlcNAc 4-epimerase that synthesizes UDP-GalNAc, the donor initiating O-linked glycosylation, would be a powerful reagent for reversibly inhibiting O-linked glycosylation. 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. Therefore, sulfation may increase the estrogenic potential of xenobiotics. We report the cloning, expression, and characterization of the first UDP-GalNAc:polypetide N-acetylgalactosaminyltransferase (ppGalNAc-T) from the human disease-causing parasite, Toxoplasma gondii. and Kirk Schanze and Lee, {T.

Bioorthogonal Labeling of Human Prostate Cancer Tissue Slice Cultures for Glycoproteomics. Still, glycoconjugate synthesis requires the manipulation of multiple stereocenters and protecting groups and remains the domain of a few expert laboratories around the world. To tackle this issue, we followed an unnatural sugar approach as bioorthogonal chemical reporters, where the use of azidosialyl residues allowed identifying the acquired sugar. Born: 10 October 1966, Boston, MA, USA. New additions to the bioorthogonal chemistry compendium can advance biological research by enabling multiplexed analysis of biomolecules in complex systems. The reaction provided a means to label the glycoconjugate-bound azidosugars with biochemical probes.

In particular, Bertozzi has advanced the understanding of cell surface oligosaccharides involved in cell recognition and inter-cellular communication. Bacteria are able to adapt to dramatically different microenvironments, but in many organisms, the signaling pathways, transcriptional programs, and downstream physiological changes involved in adaptation are not well-understood. 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. She also later developed a click reaction called the strain-promoted alkyne-azide cycloaddition, which, unlike other click reactions involving azides and alkynes, did not require toxic copper ions for the azide to snap together with the alkyne and was highly effective for tracking glycans in live cells. We report a chemical method in which the activity of an individual glycosyltransferase is controlled by a small molecule. Here, we report the development of antibody-sialidase conjugates that enhance tumor cell susceptibility to antibody-dependent cell-mediated cytotoxicity (ADCC) by selective desialylation of the tumor cell glycocalyx. View details for DOI 10.1002/cbic.200600224, View details for Web of Science ID 000241392400005. 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. Click chemistry obviates the requirement of phosphines, but the Cu(I) catalyst is toxic to cells, thereby precluding in vivo applications. These data are the first to suggest the feasibility of a strategy that improves the efficiency of gene transfer by using the biosynthetic machinery of the cell to engineer novel sugars on the cell surface. We used mass spectrometry to identify over 70 cell surface glycoproteins and biochemically validated CD146 and integrin beta-4, both of which are known to promote metastatic behavior. Fernandez-Suarez, M., Baruah, H., Martinez-Hernandez, L., Xie, K. T., Baskin, J. M., Bertozzi, C. R., Ting, A. Y. Molecular orientation of membrane-anchored mucin glycoprotein mimics. Her biography is available in 16 different languages on Wikipedia. We engineered tumor cells to display glycocalyces of various thicknesses by coating them with synthetic mucin-mimetic glycopolymers. IsoStamp has the potential to enhance any proteomics platform that employs chemical labeling for targeted protein identification, including isotope coded affinity tagging, isobaric tagging for relative and absolute quantitation, and chemical tagging strategies for posttranslational modification. Importantly, we detected increased PDIM synthesis in bacteria growing within host tissues and in bacteria grown in culture on odd-chain fatty acids. By contrast, only GlcNAc-6-SO(4) appears to contribute to MECA-79 binding. Such genetic engineering in combination with stable isotopic labeling can be applied to various metabolic pathways and their products. Glycan structural diversity is directly correlated with difficulty in characterizing the intact glycoproteome by mass spectrometry (MS). Specific labeling of biomolecules with biochemical and biophysical probes is a central element of proteomics research. We used this strategy to construct a paracrine signaling network in isolated 3-dimensional microtissues. Tsai, C., Robinson, P. V., Cortez, F., Elma, M. B., Seftel, D., Pourmandi, N., Pandori, M. W., Bertozzi, C. R. Quantitative Super-Resolution Imaging Reveals Mammalian Glycocalyx Dynamics. Lipid-derived desiccation resistance in membranes is a rare, unique ability previously observed only with trehalose dimycolate (TDM), an abundant mycobacterial glycolipid. The importance of nonclassical, multistage crystallization pathways is increasingly evident from theoretical studies on colloidal systems and experimental investigations of proteins and biomineral phases. The azidofluorescein derivative also enabled cell imaging under no-wash conditions with good signal above background. Finally, we showed that BNNTs can deliver DNA oligomers to the interior of cells with no apparent toxicity. Herein, we report the first application of this glycoproteomic platform to human tissues cultured exvivo.

Cell surface glycans govern numerous cell-cell interactions are therefore key determinants of multicellular biology. The original goal was to discuss the value of creating centers of excellence for training the next generation of biomedical investigators in the glycosciences. Here, we show that Cu(I)-FGE is functional in O2 activation and reveal a high-resolution X-ray crystal structure of FGE in complex with its catalytic copper cofactor. In this paper, an efficient enzyme kinetics assay for Stf0 using electrospray ionization (ESI) mass spectrometry is presented. Numerous factors that influence cell-surface carbohydrate composition remain to be elucidated.

Mucins and trans-sialidase (TS) are substrate and enzyme, respectively, of the glycobiological system that scavenges sialic acid from the host in a crucial interplay for T. cruzi life cycle. Very few reactions possess the requisite bioorthogonality, and, among these, only the Staudinger ligation between azides and triarylphosphines has been employed for direct covalent modification of biomolecules with probes in the mouse, an important model organism for studies of human disease. A critical branch point in mucin-type oligosaccharides is the beta 1-->3 glycosidic linkage to the core alpha-N-acetylgalactosamine (GalNAc) residue. Biomolecules labeled with azides can be detected through Cu-free click chemistry with cyclooctyne probes, but their intrinsic hydrophobicity can compromise bioavailability. Moreover, we demonstrate the efficacy of PCL-1 for monitoring physiological fluctuations in H(2)O(2) levels by directly imaging elevations in H(2)O(2) within testosterone-stimulated tumor xenografts in vivo. Studies of 4Fe-4S cluster stability and cysteine reactivity in the presence and absence of substrates, and in the free enzyme versus the covalent enzyme-intermediate (E-Cys-S-SO(3)(-)), suggest a structural rearrangement that occurs during the catalytic cycle. Thus, BARAC is a promising reagent for in vivo imaging. Wang, S., Gray, M. A., Xuan, S., Lin, Y., Byrnes, J., Nguyen, A. I., Todorova, N., Stevens, M. M., Bertozzi, C. R., Zuckermann, R. N., Gang, O.

View details for Web of Science ID 000338992200029. These screens identified CD22, a canonical Bcell receptor, as a negative regulator of phagocytosis that is upregulated on aged microglia. Thus, for applications of bioorthogonal chemistry in living systems, we built upon Wittig and Krebs' observation with the design of cyclooctyne reagents that react rapidly and selectively with biomolecule-associated azides. Characterizing their peptide and glycopeptide substrate specificity is critical for understanding the biological role and significance of each isoform. Alternatively, selective inhibition or activation of glycosyltransferases or glycosidases can define the biological roles of the corresponding glycans. Although global sulfatase activity was reduced in the mutant, a significant amount of residual sulfatase activity suggests the presence of FGE-independent sulfatases in this organism. However, the lack of chemical tools to study mucin-type O-linked glycosylation has hindered our molecular understanding of O-linked glycans in many biological contexts. The measurements indicate a detection limit of (5.6 +/- 1.1) x 10(6) L. monocytogenes in our sample volume of 20 microl. The most potent examined, 1-68A, is a pH-dependent, two-step, covalent inhibitor of Escherichia coli LpxC that competes with UDP to bind the enzyme in the first step of inhibition. and Shu Wang and Kim, {Hyun Jae} and Meyer, {Gerald J.} Stanford University biochemist Carolyn Bertozzi is a highly admired scientist, entrepreneur, and advocate for diversity, particularly for LGBTQ+ people. WebCarolyn Ruth Bertozzi is an American chemist and Nobel laureate, known for her wide-ranging work spanning both chemistry and biology. The polypeptide N-alpha-acetylgalactosaminyltransferases (ppGalNAcTs) play a key role in mucin-type O-linked glycan biosynthesis by installing the initial GalNAc residue on the protein scaffold.
