Analysis of Biomolecules

Each cell in an organism is composed of many macromolecules (called "biomolecules") that are necessary for various cellular functions and metabolism. The biological activity of biomolecules is controlled by their interactions with other molecules within the cell. This interaction is in turn controlled by their three-dimensional (3D) structure in space [1]. Therefore, understanding the structural and kinetic information of biomolecules is crucial for a comprehensive understanding of their functions. Nuclear magnetic resonance (NMR) spectroscopy is arguably the most versatile analytical method for the study of matter. It is an indispensable analytical technique that has been successfully applied to study the structure, dynamics and interactions of biologically significant macromolecules and their complexes in the solution state. Up to now, the field of biomolecular NMR has progressed rapidly, with new advances being made every year.

Our Analysis Methods

The NMR methods used in our laboratory for the analysis of biomolecules include, but are not limited to the following.

  • Solution-state NMR Spectroscopy

Solution-state NMR Spectroscopy

In structural biology, solution-state NMR plays a central role not only in elucidating the 3D structures of biomolecules such as proteins, nucleic acids and their complexes, but also in describing how these molecules fluctuate around their equilibrium positions and how they change over time under nonequilibrium conditions [2].

  • Solid-state NMR Spectroscopy

Solid-state NMR is suitable for the analysis of samples that cannot be studied in solution, such as membrane proteins or amyloid fibrils. In addition to being used to study the structure of these samples, solid-state NMR spectroscopy is also used to gain information about dynamical aspects of biomolecules.
