A great year for macromolecular crystallographers

X-ray crystallography has long been the most potent method for obtaining high-resolution structural information on proteins, nucleic acids and their complexes. In 2014, 9628 entries were added to the Protein Data Bank (PDB) to bring the total count of released structures above 100,000. In 2015 this success continued, with again more than 9000 structures released throughout the year. But it was not just the quantity of the structures. The increasing quality is something to celebrate as well.

In 2015, 148 papers in the three journals with the broadest scientific reach (Cell, Science and Nature) presented results obtained with contributions from macromolecular x-ray crystallography. These papers contained 440 crystal structures of biologically important systems, from antibodies against human pathogenic viruses (Hashiguchi et al., Impagliazzo et al., Robinson et al., Rouvinski et al., Scharf et al., Wu et al., Zhou et al.) to important trans-membrane transporters (Arakawa et al., Deng et al., Kato et al., Leung et al., Lin et al., Moser von Filseck et al., Nomura et al., Perez et al., Tao et al., Wang et al.) and proteins involved in membrane fusion (Diao et al., Rostislavleva et al., Zhou et al.). We would like to congratulate all involved researchers on their achievements.

At DECTRIS, we are proud that data from PILATUS detectors is over-represented among the highest-impact research compared to the PDB overall. Whereas 23% of the coordinate sets released in 2015 were obtained from data collected on PILATUS detectors, 37% of PDB entries published in Cell, Science and Nature were based on PILATUS data. Forty-seven of the structures reported last year in these three high-impact journals were solved by experimental phasing. In this subset where the highest data quality is essential, the share of structures solved from PILATUS data is nearly 43%. Our customers know that better detectors will help them obtain better data.

Figure 2. Structures released by the PDB are increasingly solved from PILATUS data. Shown is the annual share of structures released by the PDB that were solved with data collected with PILATUS detectors.

It is thus not surprising that we ship increasing numbers of PILATUS3 and now also its successor, EIGER, to beamlines at synchrotrons worldwide. In 2015, we installed a PILATUS3 S 2M at beamline 14-2 of Bessy II in Berlin, Germany, and a PILATUS3 S 6M at sector 5 of ALS in Berkeley, California. We also delivered one PILATUS3 X 6M detector each to SBC-CAT at APS in Argonne, Illinois, and to beamline 11C of PLS in Pohang, Korea, but the big news for crystallographers was the arrival of EIGER at the first synchrotron facilities.

In May, two EIGER X 4M detectors were installed at beamline BL-1A of Photon Factory in Tsukuba, Japan, in a V-shaped conformation inside a helium-filled chamber. This unusual setup will facilitate the collection of high-quality anomalous diffraction data at x-ray energies as low as 3.7 keV. The first EIGER X 16M, our new flagship detector, entered service at beamline X06SA of SLS in Villigen, Switzerland, in October.

In the two months that remained of the year, an EIGER X 16M was installed at beamline FMX of NSLS II in Brookhaven, New York, an EIGER X 9M at beamline Proxima-2A of Soleil in Saclay, France, and another EIGER X 9M at LS-CAT at APS. The EIGER X 9M at Proxima-2A produced data to solve the first novel protein structure less than a month after arrival of the detector onsite.

The future is bright for structural biology. Cryo-electron microscopy has just been named Method of the Year by the editors of the Nature journals. Electron microscopy and crystallography will be increasingly synergistic in resolving challenging targets, but crystallography is still growing and will dominate structural biology for most biological systems for the foreseeable future.

First EIGER X 16M in operation at the Swiss Light Source

Villigen, November 2015: The macromolecular crystallography beamline X06SA at the Swiss Light Source (SLS), a synchrotron operated by Paul Scherrer Institute (PSI), is the first one in the world to upgrade its detector to an EIGER X 16M. On 14 Oct 2015, the new detector entered service, and it is already a success. Meitian Wang, group leader and beamline responsible, is delighted with the new detector's stability. "Since its installation last month, the EIGER has operated without any problems", he said.

The EIGER X 16M succeeds a PILATUS 6M, an instrument that has led to the determination of many important protein structures and contributed to the reputation of beamline X06SA as one of the world's best. In addition to the technical specs, Wang is also excited about is the application programming interface that simplifies detector operation. The transition from the camserver of the PILATUS to the new API was a happy one.

Firmware version 1.5 delivered with the EIGER represents a very stable and high-performance release. "The system installed at SLS exceeds the specifications that we promised during the Synchrotron Radiation Instrumentation conference in July 2015", said Clemens Schulze-Briese, CSO of DECTRIS.

EIGER X 16M diffractionIn tests before EIGER went online, Wang and colleagues collected data from crystals whose longest unit cell dimension exceeded 1000 Å. Thanks to EIGER's pixel size of only (75 µm)2, data could have been collected to well beyond the resolution limit of the crystal of 3 Å. More relevant for regular users will be the continuous read-out feature, which ensures duty cycles of above 99% even when the detector runs at full speed and makes breathtakingly fast experiments possible. In separate tests, Wang was able to successfully collect an entire S-SAD dataset within one second.

Among the first users of the EIGER X 16M was Hauke Hillen, a PhD student from the Max Planck Institute for Biophysical Chemistry in Göttingen. On a recent afternoon, he was busy collecting data for experimental phasing of a crystal structure based on the sulfur signal. Between datasets, he stopped for a quick chat: "I'm very impressed with the EIGER", he said. "It's so fast." With this, the conversation was over, as he had to rush back to his experiment.

The high frame rate and large number of pixels of the EIGER X 16M lead to unprecedented amounts of raw data. To make online data processing, speedy transfer to the users' home labs and reliable archiving possible, bit-shuffle filtered LZ4 compression was introduced. This compression strategy is not only fast enough to keep up with the generated data but also more efficient than CBF compression. Vincent Olieric, beamline scientist at the PSI, was impressed that the new detector does not generate much more data on disk than the previous PILATUS 6M. "It's great for users", he said.

The development of the EIGER X 16M now operating at SLS was accelerated by a grant by the Swiss Commission for Technology and Innovation (CTI) to promote collaboration between academia and business. The detector could thus be tested under realistic experimental conditions from an early stage. Moving from prototype to final product, DECTRIS engineers and scientists have developed an instrument that meets the needs of the most exacting X-ray crystallographers. Eventually, all EIGER customers will benefit from that.

Low-dose data for high-quality structures

Villigen, March 2015: Researchers at the Swiss Light Source, a synchrotron radiation facility at the Paul Scherrer Institute (PSI) in Villigen, have developed a new approach to solving crystal structures from unmodified protein and nucleic acid crystals. Traditionally, the determination of a new protein structure depended on the calculation of the positions of exogenous heavy atoms whose incorporation is often laborious or inefficient.

Using a DECTRIS PILATUS 2M detector, PSI researchers improved a method known as “native SAD” (single-wavelength anomalous diffraction) where only atoms present in the protein are used to determine the structure. Until now, this method was limited to structures of small, well-diffracting proteins. With the new approach of collecting low-dose data at high redundancy, in multiple sweeps with the crystal in multiple orientations, the weak signal inherent in light atoms naturally occurring in protein crystals (e.g. sulfur, calcium, potassium) can be extracted reliably, in particular since radiation damage is minimized.  

The high sensitivity of the PILATUS detectors produced by DECTRIS was critical to the success of the new approach. “These detectors can record signals with low noise with a low intensity of X-ray light, which means one can determine the protein structure with a low X-ray dose,” explains Vincent Olieric, a scientist at PSI who was involved in the project. With the new, broadly applicable technique, five new structures, among them challenging targets like a human membrane protein, a protein-DNA complex and a large multiprotein-ligand complex, were solved from native protein crystals (Weinert et al., Nature Methods 12, 131–133, 2015).

STOE DECTRIS Xenocs OpenFactory: Contributing to the spirit of the IYCr 2014

The delegates received ten days of intensive training by STOE, DECTRIS and Xenocs staff as well as guest scientists in cooperation with the IUCr.

In the first lecture, DECTRIS introduced the delegates to the instrumentation for X-ray analysis: from sealed X-ray tubes and photographic films to 4th generation synchrotrons and modern detectors. Advances of single-photon-counting technology in laboratory and at synchrotron facility were presented on several examples of difficult structures, whose solution was possible only owing to the features of MYTHEN and PILATUS detectors.

In Grenoble, the delegates received theoretical and practical training on Small Angle X-ray Scattering. Four different workshops were organized at Xenocs Headquarters so that the participants could get in-depth knowledge on Xenocs sources and optics, Xenocs SAXS/WAXS systems and data treatment software, with experiments carried out on the Xeuss 2.0 SAXS/WAXS system. The delegates also visited the European Synchrotron Radiation Facility (ESRF) and more specifically the ID02 SAXS beamline.

In Darmstadt, the participants were trained in single crystal and powder XRD at STOE’s labs. The training involved one day of theoretical lectures, while two full days focused on hands-on workshops for x-ray single crystal as well as x-ray powder diffraction on the STOE IPDS 2/2T and STADIVARI Single Crystal Diffractometer, and STADI P and STADI MP Powder Diffractometer. Thereafter, the participants joined STOE’s Single Crystal User Meeting, which included several talks from guest scientists and STOE staff. As a highlight, Prof. Dr. Gautam R. Desiraju, immediate past president of the IUCR, has held his premier speech on “100 years of Crystallography: Seen through 15 small molecule crystal structures”.

The feedback of the participants was overwhelming. Next to all the knowledge being shared, it has been impressive how strong ties have been built among the participants – connecting young crystallographers from across the world in the spirit of IYCr.
