A tension-mediated glycocalyx-integrin feedback loop promotes mesenchymal-like glioblastoma. Cell-surface glycans are attractive targets for molecule imaging due to their reflection of cellular processes associated with development and disease progression. From this global analysis, we have identified a subset of sulfur-metabolizing enzymes that are sensitive to multiple regulatory cues and may be strong candidates for therapeutic intervention. DMN-Tre labeling was detected within minutes and was inhibited by heat killing of mycobacteria. No BPAS is found inside the cells. This system enables the production of glycoproteins that are functionalized for specific chemical modifications at their glycosylation sites. 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. 1-68A and a 2-dehydroxy analogue, 1-68Aa, inhibit several purified LpxC orthologues. Interactions of mucin glycoproteins with cognate receptors are dictated by the structures and spatial organization of glycans that decorate the mucin polypeptide backbone. Riley, N. M., Malaker, S. A., Bertozzi, C. R. Sensitivity optimisation of tuberculosis bioaerosol sampling. Sensitive detection of multiple islet autoantibodies in type 1 diabetes using small sample volumes by agglutination-PCR. We used these tools to perform the first site-directed mutagenesis study of a member of this sulfotransferase family, GST2. Despite reports detailing a suite of sulfated glycolipids in many mycobacteria, a corresponding family of sulfotransferase genes remains uncharacterized. The novel rodlike polymers mimic the architecture of mucin glycoproteins and feature a phospholipid tail for membrane incorporation and a fluorescent optical probe for FLIC imaging situated at the opposite termini of the densely glycosylated polymeric backbones. The galectin family of glycan-binding proteins is thought to mediate many cellular processes by oligomerizing cell surface glycoproteins and glycolipids into higher-order aggregates. In all assays, activity appeared glycosylation independent. Despite decades of accumulated knowledge about proteins and their post-translational modifications (PTMs), numerous questions remain regarding their molecular composition and biological function. Our goal with this survey is to provide a foundation on which continued technological advancements can be made to promote further explorations of protein glycosylation. 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. The utility of the reaction was demonstrated by selective modification of biomolecules in vitro and on living cells, with no apparent toxicity.

The study of glycan function is a major frontier in biology that could benefit from small molecules capable of perturbing carbohydrate structures on cells. To increase the utility of bioaerosol sampling, we present advances in bioaerosol collection and Mtb identification that improve detection yields.A previously described Respiratory Aerosol Sampling Chamber (RASC) protocol, or "RASC-1", was modified to incorporate liquid collection of bioaerosol using a high-flow wet-walled cyclone (RASC-2). Mycobacterium tuberculosis, the causative agent of tuberculosis, produces sulfated molecules that have eluded functional characterization for decades. We constructed a glycoprotein expression signature, which revealed that metastatic tumours upregulate expression of bulky glycoproteins. Bertozzi holds the Anne T. and Robert M. Bass Professorship in the School of Humanities and Sciences at Stanford University. To discover the molecular basis of this unusual role for a G protein, we biochemically characterized and solved the X-ray crystal structure of a complex between Pseudomonas syringae ATPS (CysD) and its associated regulatory G protein (CysN). An N-azidoacetylmannosamine derivative caged with a peptide substrate for the prostate-specific antigen (PSA) protease was converted to cell-surface azido sialic acids in a PSA-dependent manner. Strikingly, we found that cholesterylamine (CholA) anchored glycopolymers are internalized into vesicles that serve as depots for delivery back to the cell surface, allowing for the display of cell-surface glycopolymers for at least ten days, even while the cells are dividing.

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. Drawing on these results, we analyzed the relationship between alkyne bond angles, which we determined using X-ray crystallography, and reactivity, quantified by experimental second-order rate constants, for a range of cyclooctynes. Using this new method, the glycome analysis of cell membranes isolated from human embryonic stem cells and somatic cell lines was performed.

The discovery of novel sulfated metabolites in M. tb and related mycobacteria strengthens this hypothesis. However, because they are internalized within hours, these glycopolymers could not be employed to probe processes that occur on longer time scales. These clusters undergo a phase transition through S-layer folding into crystalline clusters composed of compact tetramers. As part of the quest for new gold drugs, we have explored the efficacy of three gold complexes derived from the tuberculosis drug pyrazinamide (PZA), namely, the gold(I) complex [Au(PPh3)(PZA)]OTf (1, OTf = trifluoromethanesulfonate) and two gold(III) complexes [Au(PZA)Cl2] (2) and [Au(PZO)Cl2] (3, PZO = pyrazinoic acid, the metabolic product of PZA) against two mycobacteria, Mycobacterium tuberculosis and Mycobacterium smegmatis.

CysQ is a 3'-phosphoadenosine-5'-phosphatase that dephosphorylates intermediates from the sulfate assimilation pathway of Mycobacterium tuberculosis (Mtb). Specific glycocalyx compositions can also induce plasma membrane instabilities to generate more exotic undulating and pearled membrane structures and drive secretion of extracellular vesicles. cis-Cyclopropanation of mycobacterial mycolic acids by pcaA drives the activation of host Vegf signaling within granuloma macrophages.

The synthesis of these trehalose analogs sets the stage for future biochemical and NMR-based studies to probe the substrate interactions of trehalose with the recently identified mycobacterial sulfotransferase Stf0. The mutant and wild-type Mtb replicated similarly during the acute phase of infection, but the mutant showed reduced viability during the persistent phase of the infection. 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.

R., Bassik, M. C., Wyss-Coray, T. The mucin-selective protease StcE enables molecular and functional analysis of human cancer-associated mucins. Traditional spectrophotometric assays are not applicable to the NodST system since no shift in absorption accompanies sulfuryl group transfer. Alterations in GalNAc-Ts expression were shown to provide huge variability in the O-glycoproteome in various pathologies, including cancer. The results also mean that distinguishing stem cells from other mammalian cells may be facilitated by the major difference in the glycosylation of the cell membrane. In nature, glycans are constructed by glycosyltransferases that are organized in an assembly line in the endoplasmic reticulum and Golgi compartment.

Tuberculosis (TB) is the leading cause of death from an infectious bacterial disease. The C-type lectins dectin-1 and dectin-2 contribute to innate immunity against microbial pathogens by recognizing their foreign glycan structures. Such genetic engineering in combination with stable isotopic labeling can be applied to various metabolic pathways and their products. Previously, we reported a method for the attachment of living cells to surfaces through the hybridization of synthetic DNA strands attached to their plasma membrane. Applications to noninvasive imaging and glycoproteomic analyses are discussed. Glycoproteins are typically expressed as mixtures of glycoforms, their oligosaccharides being generated by a template-independent biosynthetic process. Modulation of PSA expression by chemical means has a role complementary to genetic and biochemical approaches in the study of complex PSA-mediated events.
