Poly-alpha2,8-sialic acid (PSA) has been implicated in numerous normal and pathological processes, including development, neuronal plasticity, and tumor metastasis. After completing postdoctoral work at UCSF in the field of cellular immunology, she joined the UC Berkeley faculty in 1996. Hemmerich, S., Bertozzi, C. R., Leffler, H., ROSEN, S. D. FLUORESCENCE PROBES IN BIOCHEMISTRY - AN EXAMINATION OF THE NONFLUORESCENT BEHAVIOR OF DANSYLAMIDE BY PHOTOACOUSTIC CALORIMETRY. These probes enable real-time imaging of trehalose mycolate biosynthesis and mycomembrane dynamics in the laboratory as well as in clinical settings for the detection of mycobacteria in patient samples. Genomic and proteomic profiling form a basis for biological discovery. Protein glycosylation is a heterogeneous post-translational modification (PTM) that plays an essential role in biological regulation. [36] This Pharmaceuticals dissolved in 2005.

Surprisingly, the dibenzoselenacycloheptynes also abstracted hydrogen atoms from solvents such as THF or toluene, forming dibenzoselenacycloheptene products. Binda, O., Boyce, M., Rush, J. S., Palaniappan, K. K., Bertozzi, C. R., Gozani, O. Organelle Membrane Proteomics Reveals Differential Influence of Mycobacterial Lipoglycans on Macrophage Phagosome Maturation and Autophagosome Accumulation. At 60 hours after fertilization, we observed an increase in de novo glycan biosynthesis in the jaw region, pectoral fins, and olfactory organs. One of the endothelial-derived ligands for L-selectin is GlyCAM-1 (previously known as Sgp50), a mucin-like glycoprotein with sulfated, sialylated, and fucosylated O-linked oligosaccharide chains. Jewett, J. C., Sletten, E. M., Bertozzi, C. R. Targeted metabolic labeling of yeast N-glycans with unnatural sugars. Screening of a saturation mutagenesis library of the E. coli methionyl-tRNA synthetase (MetRS) led to the discovery of three MetRS mutants capable of incorporating the long-chain amino acid azidonorleucine into recombinant proteins with modest efficiency. While these lectins possess the ability to agglutinate A(1)-blood cells carrying the -GalNAc epitope and cross-link low valency glycoconjugates, only SBA showed a tendency to form intermolecular cross-links among the arrayed polyvalent mucin mimetics. The emergence of drug-resistant Mycobacterium tuberculosis strains and the widespread occurrence of AIDS demand newer and more efficient control of tuberculosis. This technique has enabled visualization of glycans in living cells and in live organisms such as zebrafish. Saxon, E., Armstrong, J. I., Bertozzi, C. R. Cell surface engineering by a modified Staudinger reaction, Tyrosine sulfation: a modulator of extracellular protein-protein interactions, Discovery of carbohydrate sulfotransferase inhibitors from a kinase-directed library. Siegrist, M. S., Whiteside, S., Jewett, J. C., Aditham, A., Cava, F., Bertozzi, C. R.

Current approaches offer a precision approaching that of genetic control. A Pragmatic Guide to Enrichment Strategies for Mass Spectrometry-based Glycoproteomics. However, controlled investigations of the relationships between glycosylation, rigidity, and extension of membrane-bound mucins or similar macromolecules are lacking, largely because of the absence of tractable experimental models. Shes been out since the late 1980s, when being a lesbian could have jeopardized her career. The azidofluorescein derivative also enabled cell imaging under no-wash conditions with good signal above background. These enzymes often comprise large families.

Through this approach, we achieved glycopolypeptides with high molecular weights and low dispersities. A., Cox, J. S., Bertozzi, C. R. Introducing genetically encoded aldehydes into proteins. Analyses revealed that recurrent GBMs have increased tension and express high levels of glycoproteins that increase the bulkiness of the glycocalyx. This heterogeneity precludes enrichment strategies that can be universally beneficial for all glycan classes. N-Carboxyanhydride Polymerization of Glycopolypeptides That Activate Antigen-Presenting Cells through Dectin-1 and Dectin-2. 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. Chemical tools have accelerated progress in glycoscience, reducing experimental barriers to studying protein glycosylation, the most widespread and complex form of posttranslational modification. Schumann, B., Debets, M., Wisnovsky, S., Agbay, A., Wagner, L., Choi, J., Gray, M., Bertozzi, C. Quantitative super-resolution microscopy reveals the architecture of the mammalian glycocalyx and its changes during cancer progression. As granuloma angiogenesis favors the infecting mycobacteria, it may be actively promoted by bacterial determinants during infection. Her recent efforts include synthesis of chemical tools to study cell surface sugars called glycans and how they affect diseases such as cancer, inflammation, and viral infections like COVID-19. A., Bertozzi, C. R. Compositional profiling of heparin/heparan sulfate using mass spectrometry: assay for specificity of a novel extracellular human endosulfatase. View details for Web of Science ID 000178916000019. 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. Here we develop a combined genetic and chemical approach that enables introduction of the diazirine photocrosslinker onto the O-GlcNAc modification in cells. Cell surface trehalose mycolates are important modulators of mycobacterial pathogenesis and host immune response. The quadricyclane ligation joins a small but growing list of tools for the selective covalent modification of biomolecules. A microdevice is developed for DNA-barcode directed capture of single cells on an array of pH-sensitive microelectrodes for metabolic analysis. Metabolic labeling of glycans with a bioorthogonal chemical reporter such as the azide enables their visualization in cells and organisms as well as the enrichment of specific glycoprotein types for proteomic analysis. See vol 283, pg 4460, 2008). K chhai 2022-ngin tet-to Nobel Fa-hok Ching . The glycosylphosphatidylinositol (GPI) anchor is a C-terminal posttranslational modification found on many eukaryotic proteins that reside in the outer leaflet of the cell membrane. Collectively, these results indicate that the distortion/interaction model combined with bond angle analysis will enable predictions of cyclooctyne reactivity and the rational design of new reagents for copper-free click chemistry. Investigation of their function has been greatly assisted by sources of homogeneous material. In the mouse genome we have found a homologous ORF that predicts a novel murine GlcNAc 6-O-sulfotransferase with 88% identity to the human enzyme. 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. Yu, S., Boyce, M., Wands, A. M., Bond, M. R., Bertozzi, C. R., Kohler, J. J. Elucidation and Chemical Modulation of Sulfolipid-1 Biosynthesis in Mycobacterium tuberculosis. In the measurement, we add 50-nm-diameter superparamagnetic magnetite particles, coated with antibodies, to an aqueous sample containing L. monocytogenes. Beam-type collisional activation, i.e., higher-energy collisional dissociation (HCD), has been a valuable approach, but stepped collision energy HCD (sceHCD) and electron transfer dissociation with HCD supplemental activation (EThcD) have emerged as potentially more suitable alternatives. To evaluate differential glycosylation in EOC caused by modulations in GALNT3 expression, we used a metabolic labeling strategy for enrichment and mass spectrometry-based characterization of glycoproteins following GALNT3 gene knockdown (KD) in A2780s EOC cells. Senaratne, R. H., Mougous, J. D., Reader, J. R., Williams, S. J., Zhang, T., Bertozzi, C. R., Riley, L. W. Lipidomics reveals control of Mycobacterium tuberculosis virulence lipids via metabolic coupling. In the paper, Dr. Bertozzi and her team described a new method of engineering an antibody to shuttle a targeted extracellular The utility of the reaction was demonstrated by selective modification of biomolecules in vitro and on living cells, with no apparent toxicity. We use this framework to assess existing data and to ask the question, "How many distinct primary structures of proteins (proteoforms) are created from the 20,300 human genes?"

This position statement originated from a working group meeting convened on April 15, 2015, by the NHLBI and incorporates follow-up contributions by the participants as well as other thought leaders subsequently consulted, who together represent research fields relevant to all branches of the NIH. This work provides a method to study the biosynthesis of fucosylated glycans in vivo. Selective chemical reactions that are orthogonal to the diverse functionality of biological systems have become important tools in the field of chemical biology. In addition, we generated a mutant M. tuberculosis strain lacking FGE. Here we report a new biocompatible CID, Tmp-SLF, which dimerizes E. coli DHFR and FKBP and has no endogenous mammalian targets that would lead to unwanted in vivo side effects. Our observations are the first reported instance of dehydration resistance provided by a membrane glycolipid. In this study, we sought to elucidate the function of papA3, a gene from the PAT locus encoding a putative acyltransferase. Unnatural intermediates are used to challenge a specific pathway, and cell surface expression of their metabolic products provides a readout of flux in that pathway and a basis for selecting genetic mutants. Directed evolution was used to improve the activity of JamB, a membrane-bound bifunctional desaturase/acetylenase. A sensitive electrospray ionization mass spectrometry-based assay was used to extract the kinetic parameters for PAP, revealing a K m (8.1 +/- 3.1 microM) and k cat (5.4 +/- 1.1 s (-1)) comparable to those reported for other CysQ enzymes. We microinjected embryos with azidosugars at the one-cell stage, allowed the zebrafish to develop, and detected the metabolically labeled glycans with copper-free click chemistry. [reaction: see text] Here we report a novel modification of our previously reported "Staudinger ligation" that generates an amide bond from an azide and a specifically functionalized phosphine. Ooi, Y. S., Majzoub, K., Flynn, R. A., Mata, M. A., Diep, J., Li, J. K., van Buuren, N., Rumachik, N., Johnson, A. G., Puschnik, A. S., Marceau, C. D., Mlera, L., Grabowski, J. M., Kirkegaard, K., Bloom, M. E., Sarnow, P., Bertozzi, C. R., Carette, J. E. A novel therapeutic modality of inhibiting the glyco-immune checkpoint axis to treat cancer. Over time, the trapped state transforms into the stable state. The azide was detected and quantified by Staudinger ligation with a phosphine probe in a microtiter plate format.

Substrate recognition, protein dynamics, and iron-sulfur cluster in Pseudomonas aeruginosa adenosine 5 '-phosphosulfate reductase. Mesenchymal-like GBMs were highly contractile and expressed elevated levels of glycoproteins that expanded their glycocalyx, and they were surrounded by a stiff extracellular matrix that potentiated integrin mechanosignalling. However, a recent biochemical study assigned the protein's function as a class IV fructose-1,6-bisphosphatase. She has been awarded the Lemelson-MIT Prize, the Heinrich Wieland Prize, and a MacArthur Foundation Fellowship, among many others. Van de Bittner, G. C., Dubikovskaya, E. A., Bertozzi, C. R., Chang, C. J. A chimera comprising the localization domain of GlcNAc6ST-1 fused to the catalytic domain of GlcNAc6ST-2 was confined to the trans-Golgi network and adopted the substrate preference of GlcNAc6ST-1.

Furthermore, we developed a biomemetic coating strategy to interface BNNTs with proteins and cells. View details for Web of Science ID 000223369800037. A 56-member glycopeptide library designed to reflect a diversity of glycan clustering was assayed for substrate activity with ppGalNAcT isoforms using an azido-ELISA. Nonetheless, the glycosylation on cell membranes remains not well characterized because of the lack of sensitive analytical methods. Cells were decorated with biotin through selective conjugation to ketone groups, and selectively killed in the presence of a ricin A chain-avidin conjugate. Both mutant synthetases label human, hamster, and mouse cell line proteins and selectively activate their azido-bearing amino acids over 10-fold above the canonical. A., Bertozzi, C. R.

Though not directly subject to mutation, we can determine glycan structure-function relationships by synthesizing defined glycoconjugates or by altering natural glycosylation pathways. This method is rapid and efficient, allowing virtually any mammalian cell to be patterned on surfaces bearing complementary DNA in under 1 h. We demonstrate this technique using several types of cells that are generally incompatible with integrin-targeting approaches, including red blood cells and primary T-cells. 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.

Goon, S., Schilling, B., Tullius, M. V., Gibson, B. W., Bertozzi, C. R. GlcNAc 2-epimerase can serve a catabolic role in sialic acid metabolism. Furthermore, their dynamic behavior in synthetic membranes mirrored that of natural biomolecules. Putative Mtb bacilli were detected in collected fluid by fluorescence microscopy utilising DMN-Trehalose. [89][90][91], Bertozzi is a lesbian and has been out since the late 1980s. Yap, M. C., Kostiuk, M. A., Martin, D. D., Perinpanayagam, M. A., Hak, P. G., Siddam, A., Majjigapu, J. R., Rajaiah, G., Keller, B. O., Prescher, J. Using a fluorescent marker tagged to the ring molecule, Bertozzi was able to track the ring compound as it bound to the glycan, in this way developing a map of the glycan location. Using this approach, we identify 133 N-glycosites spanning 58 proteins, nearly doubling the number of experimentally observed N-glycosites in the yeast proteome. A., Bertozzi, C. R., Marahiel, M.

Metabolic incorporation of d-alanine derivatives and click chemistry detection constitute a facile, modular platform that facilitates unprecedented spatial and temporal resolution of PG dynamics in vivo. Previously, we reported targeting of the blue fluorophore coumarin to cellular proteins fused to a 13-amino acid recognition sequence (LAP), catalyzed by a mutant of the Escherichia coli enzyme lipoic acid ligase (LplA). Inhibition occurs through a metabolic mechanism in which ManBut is converted to unnatural sialic acid derivatives that effectively act as chain terminators during cellular PSA biosynthesis. Our methodology should provide general access to biochemical and imaging studies of cell surface proteins, using small fluorophores introduced via a short peptide tag. Schumann, B. n., Malaker, S.

Bertozzi received a bachelors degree in chemistry from Harvard University in 1988 and a doctorate in the same subject from the University of California, Berkeley in 1993. Furthermore, Rv0516c disruption modified peptidoglycan thickness, enhanced antibiotic resistance, and activated genes in the regulon of the alternative -factor SigF. This imaging approach should further our understanding of basic metabolic processes and pathological alterations in multiple disease models. and Irmgard Chu Distinguished Professorship in Chemistry (2005); Havinga Medal, Univ. Mycobacteria, including the pathogen Mycobacterium tuberculosis, use the non-mammalian disaccharide trehalose as a precursor for essential cell-wall glycolipids and other metabolites. Nuclear translocation of Gal-1, in turn, was regulated by discrete cell-surface glycans restricted to the front of the mammary end buds. Unbound particles randomize direction by Brownian rotation too quickly to be detected. A predominantly hydrophobic aglycone site facilitates accommodation of a variety of 2-linked sialosides; a versatility that offers the potential for glycan hydrolysis across a range of biological and technological platforms. Genome-wide CRISPR screens reveal a specific ligand for the glycan-binding immune checkpoint receptor Siglec-7. To better understand how cell surface oligosaccharides function within their native context, novel chemical approaches to modulating cell surface oligosaccharides structures are now being developed. [27][41], Bertozzi became a co-founder of Palleon Pharma of Waltham, Massachusetts, in 2015. We also demonstrate that 15 proteins undergo post-translational myristoylation in apoptotic Jurkat T cells. 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.

Cells adorned with longer glycopolymers showed increased metastatic potential, enhanced cell cycle progression, and greater levels of integrin-FAK mechanosignaling and Akt signaling in a syngeneic mouse model of metastasis. Diboron reagents display minimal cell toxicity at millimolar concentrations, penetrate cell membranes, and effectively reduce N-oxides inside mammalian cells. Interest in glycoproteomics continues to surge as MS instrumentation and software improve, so this review aims to help equip researchers with necessary information to choose appropriate enrichment strategies that best complement these efforts.

Humans do not possess a homologous metabolic pathway, and thus, these enzymes represent attractive targets for therapeutic intervention. Comparison of the cDNA and genomic DNA sequences reveals that this transferase is encoded by 10 exons in a 10 kb region. The isolation of this antibody signals the potential of phage antibody libraries in the derivation of reagents specific for post-translational modifications, although the extensive screening required indicates that such antibodies are extremely rare.
