Neutrons4Science: Enter the world of neutrons! Just be curious! https://pan-training.eu/materials/neutrons4science-enter-the-world-of-neutrons-just-be-curious Enter the world of neutrons! They are a powerful and highly acclaimed tool not only for the study of condensed matter (the world we live in) but also for confirming our current understanding of physics. What's more, you don't even need to be a scientist to use Neutrons4Science. Just be curious! Neutrons and protons are elementary particles constituting the nucleus of atoms. The neutron has no electric charge but has a spin and a magnetic moment. Neutron beams - like beams of X-rays, electrons or muons - are valuable tools for studying the multitude of materials that surround us in our daily lives (alloys, magnets, superconductors, polymers, colloids, proteins, biological systems, …). However, the way neutrons interact with matter is quite unique and, as a result, it can often reveal to us what is normally hidden. With Neutrons4Science you can discover one of the many types of neutron spectroscopy. The neutron also answers questions on the very foundations of physics, helping us to solve some of the great mysteries of the universe (Is the Grand Unified Theory valid? Is there a fifth fundamental force? ...) As an example, Neutrons4Science gives you insights to a brand new method of neutron spectroscopy that takes advantage of the quantum states of this light neutral particle. Neutrons4Science lets you experience neutron science through three interactive 3D animations: • ThALES: Use a neutron spectrometer (ILL ThALES) as if you were performing a real experiment. • Magnons: Discover the spin waves that exist inside magnetic materials and understand how ThALES can observe them. • GRANIT: Discover an innovative gravitational spectrometer (ILL GRANIT) based on neutron quantum states in a gravitational field. These three educational animations were developed with the help of scientists at the "Institut Laue-Langevin", one of the world's flagship facilities for neutron science. This project was funded by the ILL and the LPSC and developed by Ipter (out of business since 2015). neutron, ILL ThALES, neutron spectrometer, Magnons, gravitational spectrometer, GRANIT general public

Seeing the chemistry in biology using neutron crystallography https://pan-training.eu/materials/seeing-the-chemistry-in-biology-using-neutron-crystallography New developments in macromolecular neutron crystallography have led to an increasing number of structures published over the last decade. Hydrogen atoms, normally invisible in most X-ray crystal structures, become visible in neutron structures. Using X-rays allows one to see structure, while neutrons allow one to reveal the chemistry inherent in these macromolecular structures. A number of surprising and sometimes controversial results have emerged from recent neutron structures; because it is difficult to see or predict hydrogen atoms in X-ray structures, when they are seen by neutrons they can be in unexpected locations with important chemical and biological consequences. Here we describe examples of chemistry seen with neutrons for the first time in biological macromolecules over the past few years. macromolecular neutron crystallography, biological macromolecules, neutron

Neutron crystallography to inform drug design targeting SARS-CoV-2 main protease https://pan-training.eu/materials/neutron-crystallography-to-inform-drug-design-targeting-sars-cov-2-main-protease Talk from one of the ILL colloqia. See colloquia list at the bottom for other talks. COVID-19, caused by SARS-CoV-2, remains a global health threat after two years of the pandemic even with available vaccines and therapeutic options. The viral main protease (Mpro) is indispensable for the virus replication and thus is an important target for small-molecule antivirals. Computer-assisted and structure-based drug design strategies rely on atomic scale understanding of the target biomacromolecule traditionally derived from X-ray crystallographic data collected at cryogenic temperatures. Conventional protein X-ray crystallography is limited by possible cryo-artifacts and its inability to locate the functional hydrogen atoms crucial for understanding chemistry occurring in enzyme active sites. Neutrons are ideal probes to observe the protonation states of ionizable amino acids at near-physiological temperature, directly determining their electric charges – crucial information for drug design. Our room-temperature X-ray crystal structures of Mpro brought rapid insights into the reactivity of the catalytic cysteine, malleability of the active site, and binding modes with clinical protease inhibitors. The neutron crystal structures of ligand-free and inhibitor-bound Mpro were determined allowing the direct observation of protonation states of all residues in a coronavirus protein for the first time [1,2]. At rest, the catalytic Cys-His dyad exists in the reactive zwitterionic state (Fig. 1), with both Cys145 and His41 charged, instead of the anticipated neutral state. Covalent inhibitor binding results in modulation of the protonation states. This information was used to design nanomolar hybrid reversible covalent inhibitors with robust antiviral properties. High-throughput virtual screening, utilizing ORNL’s supercomputing capabilities, in conjunction with in vitro assays identified a lead noncovalent compound with sub-micromolar affinity. The neutron structure of Mpro in complex with the noncovalent inhibitor was used in a structure-activity relationship (SAR) study guided by virtual reality structure analysis to novel Mpro inhibitors with imporved affinity to the enzyme [3]. Our research is providing real-time data for atomistic design and discovery of Mpro inhibitors to combat the COVID-19 pandemic and prepare for future threats from pathogenic coronaviruses. [1] D.W.
