Here we show that the cytosolic enzyme N-glycanase 1 (NGLY1, the human PNGase) is essential for Nrf1 activation in response to proteasome inhibition. This approach is compatible with a wide range of cell types, offers excellent capture efficiency, and can potentially be used to create complex multicellular arrangements through the use of multiple capture sequences. Professor of Chemical & Systems Biology and Radiology The development of rapid screening methods for probing glycosyltransferase activities is essential for advancing the field of glycobiology. Classic methods for monitoring glycans rely on molecular recognition with probe-bearing lectins or antibodies, but these techniques are not well suited to in vivo imaging. The high sensitivity and selectivity of PCL-1 for H(2)O(2), combined with the favorable properties of bioluminescence for in vivo imaging, afford a unique technology for real-time detection of basal levels of H(2)O(2) generated in healthy, living mice. Growth then proceeds by formation of new tetramers exclusively at cluster edges, implying tetramer formation is autocatalytic. Still, glycosylation remains the underexplored frontier of many biological systems. Affiliation at the time of the award: Stanford University, Stanford, CA, USA; The nematode Caenorhabditis elegans is an excellent model organism for studies of glycan dynamics, a goal that requires tools for imaging glycans in vivo.

She followed similar lines of research during her postdoctoral studies, investigating therole of carbohydrates in inflammation. We chose to use a phosphine probe because, despite their slow reaction kinetics, they remain the best-performing reagents for tagging azidosugars in mice. She coined the term "bioorthogonal chemistry" for chemical reactions compatible with living systems.

These results demonstrate the design of macromolecules with specific orientational preferences, as well as nanometer-scale measurement of their orientation. Jain, M., Petzold, C. J., Schelle, M. W., Leavell, M. D., Mougous, J. D., Bertozzi, C. R., Leary, J. We provide evidence that conserved switch motifs in the G domain of CysN allosterically mediate interactions between the nucleotide binding sites. Here, a sequence-based analysis of newly discovered mycobacterial sulfotransferase genes, named stf1-stf10, is presented. 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. The importance and complexity associated with the totality of glycan structures, i.e. In addition, the general assay architecture should be readily applicable to high-throughput screens of other carbohydrate sulfotransferases. A combination of expressed protein ligation and native chemical ligation was used to attach these analogues to the green fluorescent protein (GFP). The rapid assembly of a complex type N-linked glycopeptide mimetic was accomplished using this technique. Nonprotonatable analogs of the test compounds did not show this effect.

In an effort to mimic the high-affinity binding, polyvalent scaffolds that contain multicomponent displays of selectin-binding ligands have been synthesized. Myoblast cells were patterned with high efficiency and remained undifferentiated after surface attachment. Therefore, development of an effective new vaccine has gained momentum in recent years. This sensitive assay quantifies specific bacteria in a sample without the need to immobilize them or wash away unbound magnetic particles. 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. Carlson, B. L., Ballister, E. R., Skordalakes, E., King, D. S., Breidenbach, M. A., Gilmore, S. A., Berger, J. M., Bertozzi, C. R. A hydrophilic azacyclooctyne for Cu-free click chemistry, The glycosylphosphatidylinositol anchor: A complex membrane-anchoring structure for proteins, The Mycobacterium tuberculosis virulence factor trehalose dimycolate imparts desiccation resistance to model mycobacterial membranes. Small molecule inhibitors of carbohydrate biosynthetic and processing enzymes can block the assembly of specific oligosaccharide structures. The glycosylation of serine and threonine residues with a single GlcNAc moiety is a dynamic posttranslational modification of many nuclear and cytoplasmic proteins. In this work, we synthesized the first phosphine-luciferin probe for use in real-time BLI and demonstrated that azide-labeled cell-surface glycans can be imaged with 1 using concentrations as low as single digit nanomolar and times as little as 5 min, a feat that cannot be matched by any previous fluorescent phosphine probes.

The recently described O-glycoprotease OpeRATOR presents exciting opportunities for O-glycoproteomics. 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. Termed the CalFluors, these probes possess emission maxima that range from green to far red wavelengths, and enable sensitive biomolecule detection under no-wash conditions. 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. Carol Bertozzi, a Stanford University chemist, won the Nobel Prize in chemistry in 2022. Woods, E. C., Kai, F., Barnes, J., Pedram, K., Pickup, M. W., Hollander, M. J., Weaver, V. M., Bertozzi, C. R.

We report the discovery that boron nitride nanotubes (BNNTs), isosteres of CNTs with unique physical properties, are inherently noncytotoxic. The accumulation of an SL-1 precursor, termed SL(1278), in mmpL8 mutant cells indicates that MmpL8 is necessary for an intermediate step in the SL-1 biosynthesis pathway. This study expands the repertoire of oncogenic mutations in CSF3R that are therapeutically targetable and provides insight into the function of glycans in receptor regulation. The kinetics of this reaction are of paramount importance for studies of dynamic processes, particularly in living subjects. The average clinical sensitivity and specificity were 96% and 97%. Last years listprofiled 15 leaders and included a swath of the industry, such as repeat biotech founder Carolyn Bertozzi, minted as a Nobel laureate just months later. Therefore, sulfation may increase the estrogenic potential of xenobiotics. A., Bertozzi, C. R., Stout, C. D. A chemical reporter strategy to probe glycoprotein fucosylation. Poor diagnostic tools to detect active disease plague TB control programs and affect patient care. 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. Targets intended for clearance expose ligands that initiate their phagocytosis ("eat me" signals), while others avoid phagocytosis by displaying inhibitory ligands ("don't eat me" signals). Finally, the Delta papA2 and Delta papA1 mutants were screened for virulence defects in a mouse model of infection. 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. 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. [92] She has a wife and three sons.[93]. Bertozzi is the only female scientist to have been awarded a science Nobel prize this year, after an all-male line-up in 2021. We further generated rapamycin-inducible chimeric enzymes comprising the localization domain of a sulfotransferase and the catalytic domain of a glycosyltransferase, demonstrating the generality of the system among other Golgi enzymes. Dissecting complex cellular processes requires the ability to track biomolecules as they function within their native habitat. (2001) Glycobiology 11, 11R-18R]. Sulfotyrosine is a post-translational modification important in many extracellular protein-protein interactions, including human immunodeficiency virus infection. Roe, B.

This may be a result of BPA sulfation/desulfation providing a pathway for selective uptake into hormone-responsive cells. Born: 10 October 1966, Boston, MA, USA. In June 2015, she joined the faculty at Stanford University as an Institute Scholar at Sarafan ChEM-H. Prof. Bertozzi's research interests span the disciplines of chemistry and biology with an emphasis on studies of cell surface glycosylation pertinent to disease states. Agard, N. J., Prescher, J. A chimeric enzyme comprising the stem region of GlcNAc6ST-1 inserted between the catalytic and transmembrane domains of GlcNAc6ST-2 had the same substrate preference as native GlcNAc6ST-1. Still, glycoconjugate synthesis requires the manipulation of multiple stereocenters and protecting groups and remains the domain of a few expert laboratories around the world. The data suggest that the ppGalNAcTs can be classified into at least four types, which working together, are able to produce densely glycosylated mucin glycoproteins. This strategy requires no chemical modification of the N-glycans or stringent sample enrichment. A., Krishnan, V., Pett, C., Yu, J., Woods, E. C., Kramer, J. R., Westerlind, U., Dorigo, O., Bertozzi, C. R. CD22 blockade restores homeostatic microglial phagocytosis in ageing brains. We identified a concise disaccharide motif, GlcNAc beta 1-->6Gal alpha-R, that preserved both recognition and specificity determinants for the GlcNAc-6-0-sulfotransferase. Here we demonstrate that cell surfaces can be engineered to display synthetic bioactive polymers at defined densities by exogenous membrane insertion. The biological study of O-linked glycosylation is particularly problematic, as chemical tools to control this modification are lacking. The results from our study strongly suggest a rapid equilibrium random sequential Bi-Bi mechanism for Stf0 with formation of a ternary complex intermediate. Site-directed mutagenesis of any cysteine residue within the conserved motif led to a loss of cluster with a concomitant loss in catalytic activity, while secondary structure was preserved. Cell surface sialosides constitute a central axis of immune modulation that is exploited by tumors to evade both innate and adaptive immune destruction. Lu, C., Jones, T., Pedram, K., Bertozzi, C., Paszek, M., Cui, B. The route developed for the model compound can be readily extended to the synthesis of native SL-I as well as additional analogues for use in the investigation of SL-I's functions.

Both significantly outperform EThcD methods, indicating that ETD-based methods are not required for routine N-glycoproteomics. A., Hangauer, M. J., Bertozzi, C. R. PapA1and PapA2 are acyltransferases essential for the biosynthesis of the Mycobacterium tuberculosis virulence factor Sulfolipid-1. The 1,3-dipolar cycloaddition of cyclooctynes with azides, also called "copper-free click chemistry", is a bioorthogonal reaction with widespread applications in biological discovery. The best reagent for this application was dependent upon the specific structure of the azide. In a proof-of-principle proteomics experiment, we used metabolic GalNAz labeling of human cells and a bioorthogonal chemical probe to affinity-purify and identify numerous O-GlcNAcylated proteins. In contrast, polySia expression and function in the nervous system has been well characterized. Beatty, K. E., Williams, M., Carlson, B. L., Swarts, B. M., Warren, R. M., van Helden, P.

The GALNT3-dependent glycoproteins identified by this metabolic labeling approach support the oncogenic role of GALNT3 in EOC dissemination and may be pursued as novel EOC biomarkers and/or therapeutic targets.Knowledge of the O-glycoproteome has been relatively elusive, and the functions of the individual polypeptide GalNAc-Ts have been poorly characterized. Thus, M. tuberculosis most likely produces PAPS for the sole use of this organism's sulfotransferases.

Using these probes, chemoselective imaging of either H(2)O(2) or caspase 8 activity was performed in vitro and in vivo. After screening almost 8000 selected clones, we were able to isolate a single specific single chain Fv using two different selection strategies, one of which included elution with tyrosine sulfate. The unnatural sialic acid analog, N-levulinoyl sialic acid (SiaLev), was incorporated into cell surface glycoconjugates including PSA by the incubation of cultured neurons with the metabolic precursor N-levulinoylmannosamine (ManLev). Finally, we engineered the Golgi-resident glycosyltransferase FucT7 for tunable control by Tmp-SLF in mammalian cells. We identified and characterized a conserved mycobacterial sulfotransferase, Stf0, which generates the T2S moiety of SL-1. We demonstrated the method by constructing site-specifically glycosylated variants of the human growth hormone. Sanders, W. J., Katsumoto, T. R., Bertozzi, C. R., ROSEN, S. D., Kiessling, L. L.

Recent advances in our understanding of SL-1 biosynthesis will help elucidate the role of this curious metabolite in M. tb infection. The Staudinger ligation of azides and phosphines has found widespread use in the field of chemical biology, but the mechanism of the transformation has not been characterized in detail. 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. We also found that StcE digests cancer-associated mucins from cultured cells and from ascites fluid derived from patients with ovarian cancer. Hubbard, S. C., Boyce, M., McVaugh, C. T., Peehl, D.
