Glycans, unlike nucleic acids and proteins, are not synthesized from a template, leading to an immense structural and conformational diversity. This complexity is both a challenge and an opportunity. Our glycan crystal kinetic analysis service is designed to address this by providing a multi-faceted approach to understanding glycan behavior at the molecular level.

Our service is a comprehensive, multi-step process designed for clarity and precision, allowing us to deliver actionable insights into your project.

The process begins with a detailed consultation to understand your project goals and challenges. We require you to provide a clear project brief, including the amino acid sequence of your target protein, any available crystal structures, and information on the glycan of interest. This initial input is crucial for creating a bespoke analysis plan.

We combine several advanced technical platforms and methods to provide a comprehensive analysis of glycan behavior.

Crystallization kinetics analysis

This service monitors the crystal growth and nucleation rates of glycan solutions under varying conditions. It helps us understand the fundamental principles governing glycan crystallization, which can reveal stable, low-energy conformations that are otherwise difficult to capture. By controlling factors like temperature and pH, we can encourage the formation of well-ordered crystals, providing a solid foundation for further structural analysis. This is crucial for obtaining high-resolution data that complements our dynamic simulations.

Solubility analysis

Our solubility analysis service measures the solubility of glycan crystals across different temperatures and solvents. This helps us study the dissolution behavior and kinetics of glycan structures, providing insights into their stability and interactions with a surrounding solvent. Understanding solubility is essential for formulating glycan-based drugs and for predicting their behavior in a physiological environment.

Pressure-Temperature phase diagram analysis

This is an advanced technique that studies the kinetics of glycan crystals, including phase transitions and melting points, by adjusting temperature and pressure conditions. By mapping the pressure-temperature phase diagram, we can identify the most stable forms of a glycan and understand how environmental factors might alter its structure. This provides invaluable information for optimizing drug storage conditions and predicting a therapeutic's stability under stress.

In addition, our team builds a high-fidelity, all-atom model of your protein-glycan system by using the provided data. We leverage molecular dynamics (MD) and Brownian dynamics (BD) simulations to generate thousands of biologically relevant glycan conformations. This process allows us to overcome the limitations of static snapshots and model the intricate, dynamic dance between glycans and their protein partners.

The computational models are then rigorously validated through experimental techniques. We employ a range of state-of-the-art methods, including high-field NMR spectroscopy and Surface Plasmon Resonance (SPR), to measure kinetic parameters such as association (ka) and dissociation (kd) rates.

The verified kinetic and thermodynamic data are integrated with our Structural Analysis. We use specialized software to analyze binding pockets, hydrogen bond networks, and conformational changes. This step provides deep insights into the molecular forces driving the interaction, such as nonconventional hydrogen bonds or steric hindrance from the glycan shield. Upon completion, you receive a comprehensive report detailing our findings.

Why Choose Us?

We provide a multiscale, integrated solution that combines cutting-edge computational power with rigorous experimental validation, giving you a holistic understanding of your target system. This synergy is crucial for revealing the complex dynamics of glycans, which are often overlooked by conventional methods. Our expertise in navigating the complexities of the glycan shield and understanding multivalent interactions provides a distinct advantage. The glycan crystal kinetic analysis service provides a deep dive into the dynamic behavior of glycans by integrating advanced computational modeling with high-resolution experimental validation. This holistic approach moves beyond a static view to characterize the intricate molecular forces that govern glycan-protein interactions. By leveraging this service, we can precisely quantify the thermodynamic stability and kinetics of binding events, providing the actionable insights necessary for rational drug design and development in the burgeoning field of glycobiology.

Published Data

This research paper provides novel structural insights into how the FimH bacterial adhesin facilitates Escherichia coli adhesion by binding to N-glycan receptors on human cells. The study's central finding is a "cooperative switch" in FimH binding, which transitions from a simple one-to-one, monovalent interaction to a more stable, two-to-one, bivalent complex. This switch is driven by a subtle change in the N-glycan structure. While FimH normally binds with high affinity to the Manα1,3Man branch of oligomannose-5, the addition of a mannose molecule to this arm creates oligomannose-6. This new mannose group effectively shields the high-affinity epitope, forcing two separate FimH molecules to bind to the oligomannose-6 glycan at different locations. This positively cooperative binding mechanism means the attachment of the first FimH protein makes it easier for a second one to bind, leading to a much stronger and more stable overall attachment. The findings are highly significant for the design of new FimH antagonist molecules. The figure provides critical experimental proof for this mechanism, showcasing that a mix of the preferred Manα1,3Man and less-preferred Manα1,6Man mannose linkages leads to stronger FimH binding than the high-affinity ligand alone.
