Summary: Glycomics, focusing on the study of sugars in organisms, has gained attention due to advancements in mass spectrometry. Analyzing glycan structures associated with FSH has helped understand its biological roles, leading to the development of FSH Glycans DataBase (FGDB) for data storage and analysis to accelerate research in this field.

Summary: Oligomerization and glycosylation play important roles in the stability and efficacy of therapeutic glycoproteins, but the interplay between these two attributes is often difficult to define. In this study, a native top-down mass spectrometry approach was used to assess the glycosylation status of therapeutic cytokine and hormone assemblies and to relate interfacial glycan occupancy to complex stability. The study found that interfacial O-glycan stabilizes tumor necrosis factor-alpha trimer, while interferon-beta 1a dimerization is independent of glycosylation. Furthermore, a unique distribution of N-glycans on the follicle-stimulating hormone alpha subunit was discovered, and the interfacial N-glycan was found to interact extensively with the beta subunit to regulate dimer assembly.

Summary: This study reveals that HIV is captured near the lymphocyte surface in a virion-glycan-dependent manner. Removing certain glycans impairs virus-cell binding and interfering with glycan interactions reduces HIV infectivity. These findings provide new insights into the interaction between HIV and host cells.

Summary: This study describes the isolation, structural determination, and chemical synthesis of the N-glycan from the hyperthermophilic archaeon Thermococcus kodakarensis, revealing a unique structure including myo-inositol not found in previously characterized N-glycans. The synthesis of this glycan was successfully achieved through diastereoselective phosphorylation and phosphodiester construction by S(N)2 coupling. This research is expected to provide insights into the primitive function of glycan modification at the molecular level by considering the early divergence of hyperthermophilic organisms in evolution.

Summary: Rapid and accurate detection of foodborne pathogens is crucial in preventing foodborne illnesses. This review highlights the potential of using glycan-coated magnetic nanoparticles (MNPs) as a rapid and cost-effective solution for concentrating bacteria directly from foods. The review provides background information on MNPs, synthesis of glycan-coated particles, and analyzes existing research on the extraction of bacteria from food matrices. Comparisons are made between glycan-coated MNPs and immunomagnetic separation technique, indicating that glycan-coated MNPs are a highly cost-effective method for rapid food pathogen extraction and concentration. However, further research is needed to fully understand the mechanism and optimize its extraction capabilities.

Summary: Bifidobacterium, a genus of beneficial gut bacteria, is abundant in the microbiota of healthy infants but tends to decrease with age. Due to the negative correlation between Bifidobacterium abundance and health, there is a growing interest in maintaining or restoring their populations in the gut of individuals of all ages.

Summary: The binding of glycans to glycans plays a significant role in xenogeneic self-recognition and adhesion in sponges, cell compaction in mouse embryos, and in vitro tumor cell adhesion in mammals. This intermolecular recognition process is considered a new paradigm in cellular interactions. Glycan structures in sponges have unique species-specific sequences, and their binding mechanism relies on specific interactions of small oligosaccharide motifs.

Summary: The isolation of glycoproteins has become a convenient source of N-glycans for various applications. This study focuses on the development of a UV active linker for attaching to anomeric glycosylamines and compares its performance on glycan arrays with other linkers. The results show that the urea type linker exhibits superior performance in lectin binding and emphasizes the influence of linker choice on lectin recognition.

Summary: This study investigates the role of glycans and the energetics of glycan-mediated conformational switches in the receptor binding domains of the SARS-CoV-2 trimeric spike glycoprotein using molecular dynamics simulations and enhanced sampling methods. The findings show that the glycosylated spike has a higher barrier to opening and favors the down state. The analysis of the opening pathway reveals the interference of glycans with hydrogen bonds and the stabilization of different states. Additionally, the study explains the efficacy of a specific antibody.

Summary: Human sialyltransferase ST3GAL II was expressed in E. coli as a soluble fusion protein and utilized in a multienzyme sialylation system for high-yield production of ganglioside glycans. The lower glycosylation activity of recombinant hST3GAL II simplifies enzymatic reactions and has potential for use in automated chemoenzymatic synthetic processes in the future.

Summary: Structural biologists play a crucial role in understanding human health and disease at the molecular level. The open access Protein Data Bank (PDB) stores and provides three-dimensional biostructure data to aid in the discovery and development of therapeutic agents and diagnostic tools. The success of non-infectious mRNA vaccines, such as those developed during the COVID-19 pandemic, is based on the knowledge of 3D viral protein structures. The RCSB PDB supports vaccine designers through rigorous validation and dissemination of structure information, as well as providing tools for structure-guided design efforts.
