Title: C-Mannosylation of Proteins: Specificity and Function
Dr. Hans Bakker is a glycobiologist with expertise in glycosyltransferases. He received his Ph.D. at the VU Amsterdam, the Netherlands, and worked in Zurich, Switzerland, and Wageningen, the Netherlands, afterwards. Since 2001, he has worked at Hannover Medical School in Germany. Over the years, he has identified several new genes encoding glycosyltransferases, including the xylosyltransferases responsible for the glycosylation of Notch EGF repeats and, more recently, the first C-mannosyltransferase, the enzyme responsible for unique glycosylation of tryptophans in proteins. His laboratory has established several specific methods to characterize C-mannosyltransferases and their target proteins from Caenorhabditis elegans and mammals in vitro and cellular systems. After cloning the C-mannosyltransferase in 2013, he could establish that C-mannosylation assists in protein folding in the endoplasmic reticulum and is important for the temperature stability of proteins. Whereas C. elegans has one C- mannosyltransferase, four homologs are present in mammals. His group could show that different mammalian C-mannosyltransferases have distinct fine specificity.

Title: Complex Regulation of domain-specific O-Mannosylation by Three Non-redundant Enzyme Families
Dr. Adnan Halim is a biochemist specializing in mass spectrometry-based glycoproteomics. He obtained his Ph.D. from Gothenburg University, Sweden, in 2012, where he developed methods based on hydrazide chemistry to enrich N- and O-linked glycopeptides from human tissues. This approach led him to discover O-GalNAc linkage to tyrosine residues on amyloid-beta peptides from human cerebrospinal fluid. In 2012, Adnan was recruited to Copenhagen Center for Glycomics (CCG), where he pursued his postdoctoral training and interest in mass spectrometry, protein glycosylations, and precise genome editing. At CCG, Adnan focused on the elusive O-linked mannose modification in eukaryotes. He made major breakthroughs in this field by discovering cadherin/plexin O-mannosylations and the TMTC1-4 glycosyltransferases (GT105). Adnan was promoted to associate professor/group leader at CCG in 2016. Using a combination of techniques, including CRISPR/Cas9 engineering in cell lines and advanced mass spectrometry, his team is currently exploring the functions and regulations of non-classical O-Man glycosylations in mammalian systems.
Title: Quantitative descriptions of structure-function relationships of glycoSHIELD of coronavirus spike proteins
Dr. Danny Hsu is a Research Fellow at the Institute of Biological Chemistry, Academia Sinica. During his doctorate study at Utrecht University, the Netherlands, he determined the atomic structure of a lantibiotic, nisin, in complex with Gram-positive bacterial cell wall precursor, Lipid II. He coined the term "pyrophosphate case" to explain how nisin targets Lipid II to achieve its antimicrobial activity, providing a blueprint for future antibiotics developments. During his postdoctoral research at the University of Cambridge, UK, Danny demonstrated the proof of concept of using solution-state NMR spectroscopy to investigate the co-translational folding of nascent polypeptide chains on the ribosome. His earlier independent research focused on the folding mechanisms and functional implications of topologically knotted proteins. He currently focuses on developing an integrated biophysics and structural biology platform, including cryo-electron microscopy, mass spectrometry, and molecular modeling, to investigate the structure-activity relationship (SAR) of glycoproteins, and coronavirus spike proteins, in particular, and how mutations impact on the SAR in the context of glycosylation.
Title: Desialylation GlycoSwitch to Acutely Control Endocytosis
Professor Ludger Johannes is Research Director (DRE) at INSERM. He is a member of the Studienstiftung des Deutschen Volkes (German organization of the academically gifted), Boehringer Ingelheim Fonds, European Molecular Biology Organization (EMBO), and German Academy of Science — Leopoldina. At Institut Curie, he has been heading since 2001 the Traffic, Signaling, and Delivery Team, member of the excellence initiative Cell(n)Scale. Since January 2014, he has directed the Cellular and Chemical Biology unit. His research aims at establishing fundamental concepts of endocytosis and intracellular trafficking. The Johannes team has discovered the membrane trafficking interface between early endosomes and the Golgi apparatus, and demonstrated that lectin-induced glycolipid reorganization acts as a driving force in clathrin-independent endocytosis (termed the GlycoLipid-Lectin / GL-Lect hypothesis). The studies of the Johannes team have been published in highly visible international journals, including Cell and Nature. Between 2014-2020, he was the holder of an ERC advanced grant. He also aims at exploiting the discoveries of his team for the development of innovative cancer therapy strategies using the B-subunit of Shiga toxin (STxB) as a "pilot" for the delivery of therapeutic compounds to precise intracellular locations of dendritic cells for immunotherapy, and to tumors for targeted therapy.

Title: Mammalian Lectin Arrays for Characterizing Host-pathogen Interactions
Dr. Drickamer began working in the field of glycan-binding receptors as a postdoctoral fellow at Duke University. These receptors have been the focus of his subsequent research at Cold Spring Harbor Laboratory, the University of Chicago, Columbia University, Oxford University, and currently at Imperial College London. His work on identifying a common carbohydrate recognition led to the definition of C-type lectins as one of the major groups of glycan-binding receptors. His ongoing research is a joint project with Dr. Maureen Taylor. The aim is to develop a broad understanding of the biological roles of sugar recognition. They have used a combination of biochemical, biophysical, and molecular biological approaches to understand how carbohydrate-recognition domains provide selective recognition of glycoproteins and cell surfaces. In addition, they seek to determine how such recognition leads to the targeting of biological functions, such as innate immunity to pathogens, clearance of serum glycoproteins, cell adhesion, and cell signaling, and how genetic variation in sugar-binding receptors causes changes in their molecular properties and hence contributes to human disease. Dr. Taylor and Dr. Drickamer co-authored the textbook Introduction to Glycobiology, designed to introduce the field to students and researchers from other disciplines.
