  • Cytochrome c oxidase (CcO), the terminal enzyme in the electron transfer chain, translocates protons across the inner mitochondrial membrane by harnessing the free energy generated by the reduction of oxygen to water.
  • Understanding the 3D molecular structure of important nano-objects like proteins and viruses is crucial in biology and medicine. With recent advances in X-ray technology, scientists can now collect diffraction images from individual particles, ultimately allowing researchers to visualize molecules at room temperature.
  • Bacteria live in complex ecologies, filled with competitors, environmental dangers, and defensive hosts. They face these challenges in many ways: by gathering together into tough biofilm communities, by sharing genetic information encoding useful proteins, and by picking up and moving when things look better elsewhere.
  • The central hub for powerful electron beams at the Department of Energy’s SLAC National Accelerator Laboratory is getting a makeover to prepare for the installation of LCLS-II – a major upgrade to the Linac Coherent Light Source (LCLS), the world’s first hard X-ray free-electron laser. LCLS-II will deliver the most powerful X-rays ever made in a la...
  • World's largest X-ray laser starts operation - milestone en route to official opening on September 1. The world’s largest X-ray laser, the European XFEL, has entered its operation phase, a press release said Tuesday (July 4, 2017). The X-ray laser produces extremely bright and short X-ray flashes with the help of specialised experiment stations and...
  • Riboswitches are structurally dynamic RNA molecules, undergoing changes in shape as they perform their regulatory functions. Riboswitches typically have two domains: a ligand-binding “aptamer” domain that changes conformation when it binds to a specific ligand, which then sends a signal to an “expression platform” domain that regulates use of the R...
  • Serial femtosecond X-ray crystallography (SFX) using an X-ray free electron laser (XFEL) is a recent advancement in structural biology for solving crystal structures of challenging membrane proteins, including G-protein coupled receptors (GPCRs), which often only produce microcrystals. An XFEL delivers highly intense X-ray pulses of femtosecond dur...
  • BioXFEL researchers in collaboration with others established a procedure for serial femtosecond crystallography (SFX) in lipidic cubic phase (LCP) for protein structure determination at X-ray free-electron lasers (XFELs). LCP-SFX uses the gel-like LCP as a matrix for growth and delivery of membrane protein microcrystals for crystallographic data co...
  • UB has been awarded $4.5 million to hire world-class scholars whose work will boost the university’s research enterprise and educational offerings while enhancing innovation in the Buffalo Niagara region. The funding is comprised of three grants from SUNY’s Empire Innovation Program, which helps institutions recruit senior faculty members with trac...
  • X-ray crystallography, the workhorse of structural biology, has been revolutionized by the advent of serial femtosecond crystallography using X-ray free electron lasers. Here, the fast pace and history of discoveries are discussed together with current challenges and the method's great potential to make new structural discoveries, such as the abili...
  • Cherezov lab members in association with researchers from The Scripps Research Institute, Moscow Institute of Physics and Technology, and Institute of Complex Systems have designed, synthesized, and characterized a series of chemically stable lipids resistant to hydrolysis capable of forming a lipidic cubic phase. The phase properties and lattice p...
  • Crystal structure determination of biological macromolecules using the novel technique of serial femtosecond crystallography (SFX) is severely limited by the scarcity of X-ray free-electron laser (XFEL) sources. However, recent and future upgrades render microfocus beamlines at synchrotron-radiation sources suitable for room-temperature serial crys...

  • Designing molecules that selectively bind to a specific receptor type is often challenging, but can be crucial for different therapeutic purposes. Both angiotensin II receptors are important drug targets, since the blockade of AT1R has anti-hypertensive effects, while the modulation of AT2R could be useful for cardioprotection, neuropathic pain rel...
  • Yun-Xing Wang in collaboration with BioXFEL Researchers, publishes new article "Structures of riboswitch RNA reaction states by mix-and-inject XFEL serial crystallography" in Nature. 
  • BioXFEL member and undergraduate researcher, Fiacre Kabayiza, has created a game to help educate school-aged students on the topic of XFEL science. Employing a simple, yet engaging, tap-based gameplay and a time-proven minimal 8-bit graphical art style, he delivers a game that introduces tweens and teens to XFELs, structure determination, and the s...
  • X-ray crystallography is a technique that can be used by scientists to map the 3-dimensional physical space of proteins and other biological molecules to an atomic level of detail. Over the last four decades or so, this technique has been used to map over 100,000 protein structures that can be found in the publicly accessible Protein Data Bank, wit...
  • Researchers for years have been attempting to look at ultrafast motions at the atomic level, for example how light gets transferred into energy by plants during photosynthesis. Finally, with the use of an X-ray Free Electron Laser at Stanford, NSF BioXFEL Science and Technology researchers and collaborators from three other universities have been...
  • NSF BioXFEL researchers create a better way to find out ‘when’ An international team of physicists has created a machine-learning algorithm that improves the accuracy of timing estimates by a factor of up to 300, helping to determine when an event actually happened.
