The cell-surface repertoire can be expanded to include abiotic functionality through the biosynthetic introduction of unnatural sugars into cellular glycans, a process termed metabolic oligosaccharide engineering. Precision glycocalyx editing with antibody-enzyme conjugates is therefore a promising avenue for cancer immune therapy. Lu, C., Jones, T., Pedram, K., Bertozzi, C., Paszek, M., Cui, B. Here, we characterize Mtb's single putative type II sulfatase, Rv3406, as a non-heme iron (II) and -ketoglutarate-dependent dioxygenase that catalyzes the oxidation and subsequent cleavage of alkyl sulfate esters. Wan, S. J., Sullivan, A. Thus, choice of enrichment strategy has profound implications on experimental outcomes. Moreover, the ability of the Rv2131c-encoded enzyme to dephosphorylate PAP and PAPS in vivo was confirmed by functional complementation of an Escherichia coli Delta cysQ mutant. Main sialyl acceptors were identified as mucins by biochemical procedures and protein markers. Using in situ atomic force microscopy to follow 2D assembly of S-layer proteins on supported lipid bilayers, we have obtained a molecular-scale picture of multistage protein crystallization that reveals the importance of conformational transformations in directing the pathway of assembly. However, changes in the glycan structure significantly affected membrane mobility, with the loss of monosaccharide units correlating to decreased diffusion. Malaker, S. A., Pedram, K., Ferracane, M. J., Bensing, B. Sialylated glycans are found at elevated levels in many types of cancer and have been implicated in disease progression. Phagocytosis is the central process by which macrophage cells internalize and eliminate infectious microbes as well as apoptotic cells. Freeman, S. A., Goyette, J., Furuya, W., Woods, E.

Isotope Targeted Glycoproteomics (IsoTaG) to Characterize Intact, Metabolically Labeled Glycopeptides from Complex Proteomes. Bertozzi completed her undergraduate degree in Chemistry at Harvard University and her Ph.D. at UC Berkeley, focusing on the chemical synthesis of oligosaccharide analogs. Mucin-type O-linked glycoproteins are involved in a variety of biological interactions in higher eukaryotes. Bowman, K. G., Cook, B. N., de Graffenried, C. L., Bertozzi, C. R. The evolving academic research environment, Chemical synthesis of lymphotactin: A glycosylated chemokine with a C-terminal mucin-like domain. Thus, despite its inherent advantages in sample collection, OF is not widely used for population screening. 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. Irradiation of cells with UV light activated the crosslinker, resulting in formation of covalent bonds between O-GlcNAc-modified proteins and neighboring molecules, which could be identified by mass spectrometry. New developments have allowed researchers to begin probing the inner workings of the cell to gain new insight into cell function and metabolism.

Strikingly, this protection from dehydration extends to TDM-phospholipid mixtures with as little as 25 mol % TDM. Electron-based dissociation methods are necessary to capture the O-glycopeptide diversity present in OpeRATOR digestions. 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. Monomeric and multivalent oligosaccharides that bind to bacterial and viral receptors have been shown to abrogate infection by agents such as Helicobacter pilori, influenza virus and HIV. A broader theme that emerged was the urgent need to bring the glycosciences back into the mainstream of biology by integrating relevant education into the curricula of medical, graduate, and postgraduate training programs, thus generating a critical sustainable workforce that can advance the much-needed translation of glycosciences into a more complete understanding of biology and the enhanced practice of medicine. This review highlights the development of bioorthogonal chemical reporters and reactions and their application in living systems. N-Acetylmannosamine (ManNAc) is the first committed intermediate in the sialic acid biosynthetic pathway; thus, the mechanisms that control intracellular ManNAc levels are important regulators of sialic acid production. This provides orthogonal cleavage relative to canonical proteases (e.g., trypsin) for improved O-glycopeptide characterization with tandem mass spectrometry (MS/MS). We functionalized cells with short oligonucleotides to impart specific adhesive properties. The assay is based on the release of tritiated formaldehyde from UDP-galactofuranose but not UDP-galactopyranose by periodate and was used to identify a uridine-based enzyme inhibitor from a chemical library. Zebrafish embryos were treated with an unnatural sugar to metabolically label their cell-surface glycans with azides. The versatility of this technology was demonstrated by an example of selective drug delivery. These approaches have already identified several cancer biomarkers. GPI-anchored proteins play vital roles in signal transduction, the vertebrate immune response, and the pathobiology of trypanosomal parasites. Subsequently, the worms were reacted via copper-free click reaction with fluorophore-conjugated difluorinated cyclooctyne (DIFO) reagents. This assay allows for direct product detection on the membrane, obviating excessive washing and elution steps endemic to other assays.

Here we investigate the biosynthetic origin of H. ducreyi sialosides by metabolic incorporation studies using a panel of N-acylmannosamine and sialic acid analogues. We provide evidence that conserved switch motifs in the G domain of CysN allosterically mediate interactions between the nucleotide binding sites. A unique response factor (R) is determined for each disaccharide, whereas a multiplexed and data processing method is incorporated for faster data acquisition and quantification purposes. We developed a new fluorophore-trehalose conjugate to visualize trehalose monomycolates of the mycomembrane using super-resolution microscopy. A., Bertozzi, C. R. Investigation of the iron-sulfur cluster in Mycobacterium tuberculosis APS reductase: Implications for substrate binding and catalysis. The importance of sulfated molecules in cell-cell communication motivated us to develop a rapid two-step method for identifying these metabolites in microorganisms, particularly in pathogenic mycobacteria. However, its superior polarity and water solubility reduced nonspecific binding, thereby improving the sensitivity of azide detection. 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. Here we describe a biarylazacyclooctynone (BARAC) that has exceptional reaction kinetics and whose synthesis is designed to be both modular and scalable. Phone: (650) 721-4781. Kehoe, J. W., Maly, D.

This technique has enabled visualization of glycans in living cells and in live organisms such as zebrafish. Finally, we obtained structural and computational data that revealed the relationship between the conformation of BARAC's central lactam and compound reactivity. To accomplish this goal, we took advantage of the bioorthogonal chemical reporter technique. Here, we report the identification of the SMK biosynthetic operon that, in addition to a previously identified sulfotransferase stf3, includes a putative cytochrome P450 gene (cyp128) and a gene of unknown function, rv2269c. We used the CalFluor probes to image various alkyne-labeled biomolecules (glycans, DNA, RNA, and proteins) in cells, developing zebrafish, and mouse brain tissue slices. [4] Bertozzi is also an Investigator at the Howard Hughes Medical Institute (HHMI)[5] and is the former Director of the Molecular Foundry, a nanoscience research center at Lawrence Berkeley National Laboratory. These results establish the foundation for further development of BPDA-based colorimetric sensors. This bacterial enzyme purified from Akkermansia muciniphila cleaves N-terminally to serine and threonine residues that are modified with (preferably asialylated) O-glycans. The profile, which comprised 546 proteins, suggests diverse functions of the phagosome and potential connections to secretory processes, toll-like receptor signaling, and autophagy. Harland, C. W., Botyanszki, Z., Rabuka, D., Bertozzi, C. R., Parthasarathy, R. Crosslinking Studies of Protein-Protein Interactions in Nonribosomal Peptide Biosynthesis. Tests against related enzymes confirmed the compound's specificity for the UDP-GlcNAc 4-epimerase. Antibody reactivity was lost by antigen treatment with sulfatase or preincubation with soluble tyrosine sulfate, indicating its specificity. The structural identification of the fragments relied on the use of a variety of radiolabeled sugar precursors, further chemical and enzymatic hydrolysis, and high-pH anion-exchange chromatography analysis.

Self-assembled cellular microarrays patterned using DNA barcodes. We were able to bypass the salvage pathway by using an azide-functionalized analogue of GDP-fucose. N610 was also the primary site of sialylation of the receptor. Radioimmunoassay remains the gold standard for these challenging antibody biomarkers, but the limited multiplexability and reliance on hazardous radioactive reagents have prevented their use outside specialized testing facilities. This new protocol incorporates 12 known heparin disaccharides, including three sets of isomers. CD22 mediates the anti-phagocytic effect of alpha2,6-linked sialic acid, and inhibition of CD22 promotes the clearance of myelin debris, amyloid-beta oligomers and alpha-synuclein fibrils in vivo. Chemical tools have accelerated progress in glycoscience, reducing experimental barriers to studying protein glycosylation, the most widespread and complex form of posttranslational modification. Finally, the Delta papA2 and Delta papA1 mutants were screened for virulence defects in a mouse model of infection.
