MICROSYMPOSIA LIST

M1

Nucleic acids - protein interactions

Chairs: Marco Nardini (Milan University, IT)

Speakers: Cristiano Mota (UCIBIO, PT), Israel Fernandez (CSIC-UPV/EHU, ES)

Interactions between nucleic acids and proteins are among the most important interactions in biology because they are fundamental to key biological processes, such as replication, transcription, and recombination. The wide range of structural conformations adopted by nucleic acids and proteins plays a crucial role in their interactions. The microsymposium “Nucleic acids - protein interactions” focuses on diverse representatives of such interactions across biological systems. 

M2

Hot structures

Chairs: Marina Mapelli (IFOM-IEO, IT), Claudio Alfieri (ICR, London, UK)

Speakers: Irma Querques (Max Perutz lab, AT), Sebastian Glatt (Centre of Biotechnology, PL)

Structures of large macromolecular complexes offer invaluable insights into the intricate mechanisms underlying their roles within living cells. This microsymposium is dedicated to X-ray crystallography (MX) and cryo-electron microscopy (Cryo-EM) structures, showcasing their contributions to our understanding of biological processes. The details of the molecular landscapes provided by these structures uncover key principles governing cellular function, from enzymatic reactions to signaling cascades, and also serve as indispensable guides for the rational design of therapeutics targeting various diseases.

M3

Serial crystallography and dynamics/room temperature

Chairs: Daniele de Sanctis (ESRF, EU) - Anna Warren (Diamond Light Source, UK)

Speakers: Doeke Hekstra (Harvard University, US), Jake Hill (University of Leeds, UK)

Generally, in cryo-crystallography a static structure is obtained for the desired protein. This gives important information about the overall arrangement of atoms but doesn’t give insight into the dynamics of how this protein might behave in its native state. Moreover, cryogenic temperature might hinder structural conformations that are relevant for understanding the protein function. Ambient crystallography in combination with time resolved crystallography, where a transient species can be ‘trapped’ and probed at different intervals throughout a reaction pathway, can be combined to study the dynamics of macromolecular systems and reveal biologically important intermediates and biological mechanisms. This microsymposia will look at recent developments in all areas of room temperature, serial and time resolved crystallography, both in methodology and scientific results obtained.

With about 100 protein structures determined by 3D ED deposited in the PDB so far, on only 25 different proteins, 3D ED is not yet a main player in structural biology. However, the technique is going to benefit from the huge development of cryo-EM equipments worldwilde and the number of structural biology laboratories with access to a 3D ED facility will increase rapidly. This microsymposium will welcome works on either methodological developments in 3D ED or new structural biology results that use 3D ED.

Correlate molecular structure with materials properties

Chairs: Kresimir Molcanov (Institut Ruđer Bošković, HR), Vania Andrè (University of Lisbon, PT)

Speakers: Anna Krawczuk (University of Göttingen, DE), Jeremy Rawson (University of Windsor, CA)

New materials with targeted physical properties are an area of current interest from both, fundamental and applicative points of view. Molecular materials are chemically tunable and thus good candidates to reach this goal. They can exhibit a single property such as gas storage, sensing, magnetism or catalysts, but they can also be multifunctional with two or more physical properties of interest. Thus, bulk properties of a material stem from structure of its constituent molecules. A clever choice of the constituent molecules could allow the appearance of an unusual combination of physical properties in the same compound, or even a mutual interplay or synergy of the properties involved.

Crystallographers, as all scientists, use various concepts and computing tools to solve problems and tackle data analysis. However, the actual mode of action is often not well understood and the researchers are not fully aware of how the applied methods work. The aim of this microsymposium is to find a way to peek inside 'the black boxes' by identifying key features on which the used approaches rely, which help to avoid common mistakes and provide useful tips.

Understanding and controlling the structural and energetic factors which drive the supramolecular arrangement in crystals, is still a matter of great importance today in order to be able to produce materials with the desired properties. Hence the relevance of  polymorphism in many area (chemistry, materials, pharmaceutics), given that polymorphs can greatly differ as for their chemical, physical, thermodynamic and mechanical properties, just to name a few. This microsymposium  will provide an opportunity to present relevant results in which polymorphs formation is investigated under different conditions and with different techniques.

Chairs: Philipp Hans (SESAME, JO), Ghazala Sadicq (CCDC, UK)

Speakers: Jessica Wade (Imperial College, London, UK), Helena Butkiewicz (University of Warsaw, PL)

This microsymposium aims at shedding light on the concepts of diversity, equality and inclusion with respect to social group dynamics. Mainly, it wants to raise or create awareness in the mainstream for people outside of the mainstream, to sensitize and give perspectives. On the basis of success stories and other personal perspectives, we want to show ways of dealing with and overcoming barriers. The focus can be broad and should not be seen as restricted to a special aspect. Contributors are encouraged to be aware that criteria such as social status, age, health concerns, issues like mobbing, language and many more can be addressed in this micro symposium which also aims to be a forum for everyone. Empirical evidence should be presented to examine the possibilities and benefits of inclusive and enabling behaviors to the community, pros, cons and obstacles in both directions. We want to understand factors that lead to individuals not being invited to a certain zone as well as factors that lead to actors not taking chances and anything complementary.
