1.1.1: Closing the R-Factor Gap in Protein Crystallography

 

In macromolecular crystallography, the agreement between measured and predicted structure factors (Rcryst and Rfree) is seldom better than 20%, much larger than the estimate of experimental error (Rmerge), and an order of magnitude worse than in small-molecule crystallography.  This poor agreement is not due to experimental noise or inaccurate model phases, but appears to reflect a fundamental inadequacy in the models used to explain the observations.  What information might be missing from our models, and how much more might crystallography tell us about macromolecular structure and function with improved models?

 

This session will explore ways in which current models of the protein, solvent, and crystal may be deficient, recent attempts to address these deficiencies, and experimental and/or theoretical constraints/insights that are needed to guide further development.

1.1.2: Structural biology of nucleic acids and protein-nucleic acid complexes 

 

This session explores the latest discoveries in nucleic acid form and function with a focus on ncRNAs, as well as the structure and biogenesis of protein-nucleic acid complexes. Preference for oral presentations will be given to descriptions of ncRNA gene regulatory mechanisms with implications for drug discovery, as well as large assemblies whose structure provides insight into the underlying biology. These areas of structural biology have been catalyzed by advances in XFEL technology and cryoEM, which have enabled the structural analysis of dynamic RNAs and large protein-nucleic acid complexes that have defied the use of canonical crystallographic approaches. These advances will be highlighted along with other complementary approaches.

1.1.3: Dynamic Crystals as Molecular Materials

 

This half-day session is devoted to dynamic crystals, specifically the design, synthesis and study of crystalline molecular systems that exhibit dynamic properties. Dynamic crystals will be highlighted as a first step toward a new generation of molecular materials with modifiable physical properties, facile solid state reactions, or controlled responsivity to external stimuli (e.g., mechanical, chemical, thermal, etc.). The macroscopic properties in the target materials arise from changes in the arrangement of weakly bonded molecules in a molecular crystal. Participants are invited to submit abstracts related to: mechanical dynamics within the crystal structure; plasticity of molecular crystals; phase transitions in crystalline materials; dynamic host-guest relationship in inclusion compounds; solid state reactivity in molecular and supramolecular crystals.

1.1.4: Neutron and X-ray Scattering of Correlated and Quantum Materials

 

There is considerable recent interest in magnetic materials which show strong electron correlation and spin orbit coupling, geometric frustration and quantum effects which lead to exotic ground states. These include spin ices, spin liquids, collective spin singlets, Kitaev quantum spin liquids and others. The interest in these effects is partly driven by the potential to transform critical technologies (e.g., quantum computing, energy efficient electronics). Neutron and x-ray scattering are often the most revealing probes of these unusual phenomena, for studies of topology and for characterizing excited states. In this session recent progress from studies of materials exhibiting such exotic behavior using neutron and x-ray scattering methods, both elastic and inelastic, will be highlighted.

1.2.1: Structural Dynamics - In honour of Phil Coppens


This special session of the Annual Meeting of the American Crystallographic Association is dedicated to the late Professor Philip Coppens for his lifetime of outstanding scientific achievements and dedication to serving the broader scientific community. Philip authored over 430 peer-reviewed publications. His contributions impacted every aspect of charge density theory and application as well as the development and application of time-resolved X-ray diffraction methods to monitor light-induced structural transformations in small molecule systems.


In 2006 Philip was awarded the triennial Ewald Prize of the International Union of Crystallography at the Florence IUCr Congress for contributions to developing the charge density field and the crystallography of molecular excited states. In addition to serving on a number of editorial and scientific advisory boards, Philip also served as President of the American Crystallographic Association and President of the International Union of Crystallography.


This session will showcase recent advances in structural science using X-ray diffraction that are inspired by his impactful scientific legacy.

1.2.2: Hybrid Techniques

 

The hybrid methods session will focus on the increasing impact of SAXS on the study of biological macromolecules due to the newly developed ability to combine SAXS instrumentation with purification apparatuses, and a variety of other biophysical analysis tools. The ease with which different kinds of microfluidic chips and mixers can be integrated into a SAXS camera has led to significant developments in the field of time-resolved SAXS, which affords us the ability to study structural alterations during processes such as protein / nucleic acid folding, enzyme-substrate binding, ligand binding etc.

1.2.3: Neutrons as Complimentary Probes for Crystals and Scattering

 

This session will focus on the role of neutrons in protein crystallography and small angle scattering which offer complementary data to X-rays enabling us to understand evermore complex systems. Understanding how the structure and dynamics of an enzyme system governs function through the catalytic steps of an enzyme and binding of ligand remain a major challenge in molecular biophysics. For example, many biologically important reactions depend on the transfer of protons, and a complete understanding of the catalytic power of enzymes requires knowledge of the protonation status of residues throughout the reaction pathway. The uniqueness of neutrons is in their fundamental physical properties, which result in the strong scattering from the lightest atoms in the Periodic Table, and in the neutrons' benignity towards biological samples. Small angle neutron scattering (SANS) coupled with contrast matching for the study of biological systems offers fundamentally new, direct information that can only be inferred from most other techniques. SANS is particularly useful for studying the binding of DNA and protein-protein associations in complexes that cannot be crystallized.

1.2.4: Forefront of Electron Scattering for Nanoscale and Metastable Materials / Electron Diffraction

 

Electron scattering techniques offer unique opportunity to probe a variety of structural origin, including lattice, electronic, magnetic and chemical information, of materials' functionalities. This session is to demonstrate the latest development and applications of electron probes with particular highlights on ultrafast, in situ and multimodal techniques. Those researches using electron scattering techniques result in quantitative structural analysis visualized in more-than-three dimensions, with 3D in crystallography and additional dimension in time-domain, energy-space and/or chemical mapping.

1.3.1: Career Development

 

This session will feature resume/CV critiques for scientists beginning their careers.


The session will begin with a short talk by Brad Conrad of the American Institute of Physics (AIP) on how to present one's ideas to varied audiences (particularly in Career / job application). Effective advertising of one's skills and techniques is a necessary skill but one that is frequently not discussed within academia or crystallographic work.


This professional development session will bring together experts of varied career experiences to work one-on-one with young scientists (who have preregistered for the event) to examine how they can improve their written and verbal communication skills to potential employers. No abstracts will be accepted for this session.

2.2.5: Materials for Energy Conversion & Storage

 

The development of new technologies for electrical energy production, storage and conversion is critical to the long-term security of national and international energy infrastructure, spanning a whole range of applications, from electrical grid to electric vehicles to personal electronic devices. Operation of these energy storage devices is governed by phenomena that span multiple length and time scales. Incisive characterization tools are essential to advance our fundamental understanding of these phenomena and how they ultimately impact. Gaps exist in our understanding of charge transfer, mass transport and structural changes that impedes the rational optimization of capacity, charge rate, lifetime and safety. The goal of this session is to provide a broad overview of neutron and X-ray scattering studies on materials that address key energy-related problems, including but not limited to new battery materials and solar technologies.

2.3.1: Would You Publish This?

 

When is a structure too poor to publish? How much should scientific impact affect this decision? What are some recommended procedures for publishing poor quality structures?

3.1.2: Best practices for building, refining, and analyzing ligands in macromolecular structures

 

The proper handling of ligand identification, placement, and refinement is at the core of important research in drug discovery, biomedical science and biotechnology. One motivation for this session is an alarmingly high number of structures being deposited in the PDB with dubious ligands. In this session we will review the current best practices regarding ligands in structural biology as well as review illustrative case studies from industry and academia. This session should be especially attractive to graduate students and postdocs in macromolecular crystallography.

3.1.4: Next Generation Sources/SAS @ New Sources

 

Over the last couple of years, a number of new research infrastructures have arrived that give through the hugely increased flux and enhanced coherence, new opportunities to experiments using diffraction and scattering based methods. With more infrastructures engaged in or planning upgrades this session aims to highlight some of the facilities that have become available or are being planned. In addition, the latest advancements in SAS science exploiting the characteristics of these new sources will be showcased.

3.1.5: Crystallography at Extreme Conditions

 

This session is meant to focus on experiments and challenges in crystallography measured at extreme pressure or temperature conditions. The study of matter at extreme conditions has lead to innovations in a wide variety of fields, such as geophysics and energetic materials, as well as advances in our understanding of chemical bonding relevant to planetary evolution and the formation of life. However, the application of crystallographic techniques at nonstandard pressures and temperatures brings a large suite of challenges to the enterprising scientist. In many cases, angular range is severely restricted, x-ray  transmission is low, sample size is microscopic, and/or diffraction peaks may greatly broaden. In some cases, the chemical interaction between the desired sample and its environment is unexpected or not well understood at the experimental conditions. Fortunately, the collection of data at synchrotron facilities serves to greatly enhance data quality, enabling in situ experimentation simultaneous with diffraction. Additionally, technological advances in experimental devices such as the diamond anvil cell and creative efforts in sample alignment have allowed for improved data collection, greatly enhancing the region of reciprocal space collected in samples such as these. However, these experiments are often heroic, and extracting crystal structures and understanding the physics of materials under extreme conditions is not a trivial endeavor. Here we mean to present the state of modern crystallography at high pressure and temperature conditions, and to explore the challenges of the technique going forward and victories that many have had thus far, particularly in the fields of physics, chemistry, and geoscience. We hope that this session will allow participants to get an insight into how they can push the boundaries of their data. Abstracts on high pressure, high temperature, or unique atmospheres will be considered.

3.2.1: Structural Biology of Inherited Metabolic Disorders: Personalized Biochemistry and Biophysics

 

Inherited metabolic disorders are caused by genetic variations that negatively affect protein

function. Thousands of missense mutations in hundreds of proteins have been implicated as

causing disease, yet the structural and functional consequences are known for only a small

fraction of these cases (1). These mutant proteins represent a grand challenge to the structural

biology and biochemistry communities to establish the mechanistic linkage between pathogenic

variations and their physiological consequences, providing a rational basis for treatment or

preventive care (2). This session will bring together structural biology researchers - both

experiential and computational - to present the current state of the field of personalized

biochemistry and biophysics and discuss the challenges and opportunities for future research

aimed at developing high resolution personalized medicine.

3.2.4: Scattering Strategies in Biomembrane Research

 

The structure and function of cellular membranes in biology remains among the most challenging areas in both the life and physical sciences. Cellular membranes are complex, mesoscopic assemblies that are much more than simple permeable barriers or passive matrices for proteins; rather, they play an active role in many cellular functions, and they have a rich metabolism of their own. An understanding of cell membrane structure, dynamics and maintenance is pivotal for understanding its biological functionality. For biophysical investigations of biomembranes and small membrane-bound molecules, it is important to consider perturbations that might be caused by extrinsic probes. For example, the use of bulky lipid fluorophores can in some cases alter the physical properties of the bilayer. Neutron and X-ray scattering techniques are intrinsically probe-free and therefore offer a means to overcome this issue. Moreover, significant strides have been made in recent years to develop model membrane systems that more faithfully mimic the properties of biological membranes, and which lend themselves to investigation via scattering techniques. This session will allow ideas to be shared regarding the development new strategies and experimental platforms to investigate biological membranes using probe-free techniques.

4.1.2: Minding the Gap: MX to XFEL / Open Science

 

The serial crystallography (SX) method, originally developed at X-ray free-electron lasers (XFELs) to examine sub-micron protein crystals has been quickly adapted for use at synchrotron beamlines; new sample delivery methods, both fixed target and injector based developed at synchrotron facilities has resulted in a wider range of sample environments available at XFELs. The drive to develop common data processing frameworks for multicrystal single shot and oscillation experiments has also caused a major revival in crystallographic software developments. This session will explore the interplay between XFELs and synchrotrons and how it contributes to advances in X-ray sourced based macromolecular crystallography.

4.1.4: Application of SAS to Complex Mixtures

 

A prerequisite for detailed SAS analysis is having a well described ideally monodisperse sample for data collection. Inline size-chromatography SAS is one method of removing aggregates or separating different species just before the SAS measurement. It has been attracting considerable attention over the last several years in the SAS community and has been implemented in one way or another at most SAS beamlines at synchrotrons around the world. This session is dedicated to methods - such as chromatography coupled SAS but not limited to it - on how to deal with the non-ideal but often more realistic situation of a mixed sample in small angle scattering.

4.2.1: Regulation of Protein Function by Shape Shifting

 

Many proteins have a primary sequence that can assemble or reassemble to vastly different folded structures. These different assemblies can readily interconvert and accommodate different capabilities. This phenomenon is particularly intriguing for multi-domain proteins for which hinge motions cause alternate monomer conformations that dictate different assemblies. Two notable examples are porphobilinogen synthase for which alternate oligomers provide allosteric regulation of enzyme function; and the Ebola virus VP40 protein for which alternate oligomers account for alternate essential viral functions. This session will explore other shape shifting proteins, their structure-directed functions, and the biological triggers of structural transformation. We want to hear about your multi-structure molecules.

4.2.4: Powder Diffraction of Industrial and Pharmaceutical Materials

 

This session will focus on recent advances in the methodology for solving crystal structures from powders and results on industrially-relevant materials and processes.  Powder diffraction undertakes many roles in the pharmaceutical and other industries. Besides traditional crystal phase identification, it is used in the study of solid-state reactions, phase behavior under industrial processing, lead optimization, salt and co-crystal screening for the development of solid drug delivery forms, polymorphism studies, solid-state studies involving solvation/desolvation, etc. Crystal structure determination from powders is very valuable when single crystals cannot be obtained, or the properties of single crystals and powders may differ. Powder diffraction studies are often carried out in combination with other solid-state techniques, such as NMR, FT-IR spectroscopy, DFT calculations, thermogravimetry and differential scanning calorimetry, among others.

4.2.5: Crystallography in Synergy with Computation, Spectroscopy and Synthesis 

 

This session will stress the advantages of multidisciplinary approaches to solving complex chemical and physical problems. The synergy among crystallography, computational modelling, NMR and other spectroscopic techniques, and less commonly used techniques such as neutron inelastic scattering will be put front and center. That chemical synthesis can also be informed by these characterization techniques is well established, and presentations emphasizing this interactivity will be welcome. We hope, once again, to emphasize the importance for crystallographers of using a multidisciplinary approach and to stress the importance that crystallographic results have in the study of chemical and biochemical reactivity.
