Glycobiology

The Analytical Service and Training Laboratory at the CCRC has expertise in structural characterization of glycoconjugates including polysaccharides, glycoproteins  (Glycomics and Glycoprotemics) and glycolipids using mass spectrometry (MALDI-MS, LC-ESI-MS/MS), GC-MS ) and 1D and 2D NMR.…

The Edison lab develops new approaches in metabolomics and natural products research. Our primary research tool is NMR spectroscopy, but we regularly collaborate with experts in mass spectrometry. A major focus is on data integration between NMR, MS, and other quantitative measurements. We have…

Short Biography:

Dr. Haltiwanger received his B.S. in Biology (1980) and Ph.D. in Biochemistry (1986) from Duke University. He went on to do postdoctoral work at Johns Hopkins University School of Medicine, and took his first independent position as an Assistant Professor in the…

We are studying how nutrients regulate signaling and transcription by O-GlcNAcylation (OGN). OGN is the addition and removal of N-acetylglucosamine from Ser(The) residues of nuclear, cytoplasmic and mitochondrial proteins. The cycling sugar is analogous to phosphorylation and has extensive…

Biosynthesis and Biological Function of Pectin

What is Pectin?

The cell wall of plants is a polysaccharide and protein rich macromolecular structure that is essential for plant form and function. It is also the meeting point between the plant and its symbionts or pathogens. Pectin…

Research in the Moremen lab focuses on the structure, regulation, and localization of enzymes involved in the biosynthesis, recognition, and catabolism of mammalian glycoproteins. Carbohydrate structures on glycoproteins contribute to many biological recognition events during development,…

Research in the Prestegard laboratory focuses on nuclear magnetic resonance (NMR) methods development and application of those methods to challenging problems involving soluble proteins, membrane proteins, cell-surface carbohydrates, and carbohydrate-protein interactions. Many of these systems…

The surfaces of all eukaryotic cells are richly endowed with a diverse array of complex glycoconjugates. Therefore, carbohydrate moieties linked to protein, lipid, and glycosaminoglycan form the interfaces at which cell-cell interactions occur. Consistent with their subcellular location and…

Glycosylation plays a variety of roles in basic biological processes, and alterations in these carbohydrate structures contribute to many human diseases. The mammalian glycome contains extensive structural and functional heterogeneity that can vary temporally and spatially during development and…

Our laboratory examines how post-translational modifications (primarily glycosylation) increase functional diversity of proteins.  We are focused on congenital disorders of O-glycosylation that includes forms of X-linked intellectual disability (defects in the O-GlcNAc pathway; OGT-CDG,…

Research Areas

Oxygen Sensing

In addition to its role in driving oxidative metabolism, ambient O2 levels carry information of great interest to cells of both unicellular and multicellular organisms. For example, O2 regulates gene expression and modulates ion transport across…

My lab studies the relationship between protein structure and function, and specifically how enzyme activity is regulated. To do this, we use a combination of techniques, including X-ray crystallography, transient and steady state kinetic, sedimentation velocity and other biophysical tools.…

Research in the Woods group examines the relationship between carbohydrate conformation and biological recognition. Areas of particular interest include carbohydrate antigenicity in immunological events, carbohydrate- processing enzymes, and the development of appropriate simulational methods…
