Research Groups

Ilme Schlichting Group - Coherent diffractive imaging

Structural biology, and in particular scattering based techniques making use of X-rays and electrons, has provided high-resolution insight in the structure and function of molecules, molecular assemblies, and cells. Despite a lot of advances in instrumentation, radiation damage limits high resolution imaging of biological material using conventional X-ray or electron based approaches. X-ray free-electron lasers (FELs) exceed the peak brilliance of conventional synchrotrons by almost 10 billion times. They promise to break the nexus between radiation damage, sample size, and resolution by providing extremely intense femtosecond X-ray pulses that pass the sample before the onset of significant radiation damage.


Ilme Schlichting Group - Photoreceptors

Since light is an important environmental variable, many organisms have evolved signalling pathways that transmit and thereby translate this stimulus into various biochemical activities. Recently, new classes of blue light photoreceptors have been identified that use flavin based photosensors. The photosensor domains are coupled to an array of other domains, including kinases and transcription factors. We are studying proteins containing LOV and BLUF domains as photosensors using crystallographic, biochemical, and quantum chemical approaches. Together with spectroscopic data, their combination allows to understand on a molecular level how absorption of a blue light photon results in a specific structural change of the protein that triggers a secondary signal resulting in a biological event.

Jochen Reinstein Group - Molecular Chaperones

Attaining a well defined three dimensional structure and thus functionality can be a serious challenge in the early life of many proteins. Although the final structure is energetically favored, many side reactions can occur mostly leading to aggregation that prevent the formation of the native protein structure. Molecular chaperones are ubiquitous in prokarytic/eukaryotic organisms and form cellular networks which assist protein folding in the cell. [more]

Anton Meinhart Group - RNA Processing / Bacterial Programmed Cell Death

RNA is the exclusive messenger that forwards genetic information for protein synthesis to the ribosome. In eucaryotic organisms, genes are transcribed into messenger RNA (mRNA) by RNA polymerase II in the nucleus. The pre mRNA resides in the nucleus and becomes processed until the mature mRNA can shuttle into the cytosol via the Nuclear Pore Complex. [more]

Robert Shoeman Group - Analytical Protein Biochemistry

The performance of instrumentation for the precise biochemical characterization of proteins has increased dramitically in recent years, primarily as a result of improvements in computer hardware. This is particularly obvious in the field of mass spectrometry, where newer instruments show increases in resolution and sensitivty of more than 1000-fold over instruments dating from the year 2000, and in robotics, where sophisticated as well as dedicated instruments have become affordable and usable, even for small groups of users.

Tatjana Domratcheva Group - Computational Photobiology

Sunlight is an important environmental factor and light-induced chemical reactions may have both beneficial and detrimental biological effects. Photon absorption produces highly reactive excited molecules which can undergo chemical changes. [more]

Thomas Barends Group - Structural Biology of Elemental Cycles

The discovery of anammox bacteria in the 1990's has dramatically changed our understanding of the global nitrogen cycle. These bacteria perform ANaerobic AMMonium Oxidation (ANAMMOX), combining ammonium with nitrite into molecular dinitrogen (N2) and water, yielding energy for the cell. This process relies on highly unusual intermediates such as hydrazine. We are studying the molecular mechanism of the ANAMMOX process using structural biology. [more]
