atoms<\/a> and therefore analyse the atomic structure of molecules.<\/p>\nDennis Kurzbach and his research team have based their study on nuclear magnetic resonance (NMR), which enables them to observe biological processes in real-time. By utilising hyperpolarised water, scientists significantly developed the NMR signals of the examined samples and were able to boost the method\u2019s sensitivity.<\/p>\n
Hyperpolarised water: A booster for the NMR signals<\/h3>\n By utilising hyperpolarisation methods \u2013 or dissolution DNP (D-DNP) \u2013 a signal enhancement of over 10,000-fold is possible. \u201cThe hyperpolarised water acts as a booster for the NMR signals of a protein during the measurement. The hydrogen nuclei of the hyperpolarised water are exchanged with those of the proteins, thus transferring the signal strength to the latter,\u201d explained Dennis Kurzbach from the Institute of Biological Chemistry and Deputy Head of the NMR Centre of the Faculty of Chemistry.<\/p>\n
Therefore, this method means that scientists are able to record an NMR spectrum every 100 milliseconds, which allows them to track the 3D coordinates of each individual amino acid and how they change over time. \u201cThis allows us to monitor processes that occur in milliseconds and distinguish individual atoms,\u201d added Chemist, Dennis Kurzbach.<\/p>\n
What does this new method mean for science?<\/h3>\n Researchers have documented their new technique in detail, from hyperpolarisation to the transfer of the hyperpolarised water to the NMR spectrometer, to the mixing of the hyperpolarised water with the sample solution, and the NMR measurement.<\/p>\n
Additionally, six examples for method application were presented, including the observation of protein folding as well as the interactions of RNA (nucleic acids) and RNA-binding proteins as the basis for gene expressions in the cell. According to scientists, this new method can be utilised for specific studies of RNA, DNA, and polypeptides, especially when signal enhancement reaches the \u2018magic\u2019 number of 1,000-fold.<\/p>\n
Thus, an NMR spectrometer that has been equipped with a hyperpolarisation prototype is a prerequisite for NMR and is boosted by hyperpolarised water. However, this infrastructure is currently not widely employed. The Faculty of Chemistry at the University of Vienna has been equipped with a DDNP-NMR device since 2020, which was constructed by Dennis Kurzbach and based on an ERC Starting Grant.<\/p>\n","protected":false},"excerpt":{"rendered":"
Researchers from the University of Vienna have revolutionised the nuclear magnetic resonance method to monitor fast and complicated biomolecular events, such as protein folding. A scientific research team, including Dennis Kurzbach from the University of Vienna\u2019s Faculty of Chemistry, has recently published their revolutionised method of nuclear magnetic resonance in the journal Nature Protocols.
