分辨率更上一层楼：解决社会面临的挑战

他们的研究包括重要的球状蛋白、膜蛋白和蛋白复合体的结构、动力学和功能。

超高场核磁共振是独一无二的，它可以研究内在无序蛋白（IDPs）的属性和相互作用，这些蛋白质占人类蛋白质组的30-50%。IDPs 在基本的细胞生物学中发挥着关键的功能规则，它们也在许多疾病生物学案例中有所体现。

The Bio-NMR group, headed by Roland Riek, is part of the Laboratory of Physical Chemistry at the Department of Chemistry and Applied Biosciences of the Swiss Federal Institute of Technology (ETH) Zurich.

Nuclear Magnetic Resonance Spectroscopy (NMR) is one of the principal experimental techniques in structural biology to determine atomic resolution structures and to investigate dynamic features and intermolecular interactions of biological macromolecules. Using NMR as a major tool, the objective of the research in our group is to understand the conformational switches of proteins associated with amyloid diseases and trans-membrane signaling.

The function of each cell and each organism decisively depends on the dynamic interactions between biological macromolecules and on their correct three-dimensional structure. Faulty interaction and incorrectly folded structures eventually lead to diseases and ageing. 

The aim of the Institute for Physical Biology at the Heinrich Heine University of Düsseldorf is to understand these interactions and to determine the three-dimensional structure of the protein complexes involved in decisive cellular processes - if possible, in atomic resolution.

They are interested in understanding the structural features of life's key players and to use their insights to identify new therapeutic opportunities to interfere with disease-related processes. 

In this respect the Etzkorn Group at the Institute for Physical Biology of the Heinrich Heine University Düsseldorf focuses on the following topics:

Membrane systems in neuronal signalling, NMR method development, Biocatalysis.

The uNMR-NL facility enables non-invasive characterization of molecular systems from the atomic to micrometer range by ultra-high field NMR. The current uNMR-NL high-end 1.2 GHz spectrometer is equipped with state-of-the-art instrumentation for all fields of research needed, providing the highest sensitivity and resolution in the Netherlands.

In this interview, Jesús Jiménez-Barbero, the scientific director of CIC bioGUNE in Bilbao, Spain, discusses his research on the role of sugars (glycans) in cellular interactions. Using NMR spectroscopy, his team studies how these flexible molecules interact with other cells and pathogens. He highlights advancements in NMR technology, including a new GHz instrument, which enhance their ability to analyze complex glycoproteins and their interactions, particularly in the context of viral infections and cancer. This research aims to develop new therapeutic strategies by understanding these molecular interactions.
