However, there is a need for new pharmaceutical alternatives, since not all patients respond to the existing medicines. Thanks to the research partly carried out at the European Synchrotron Radiation Facility (ESRF), it is now possible to tailor new molecules that can block the LTC4 synthase. “I believe this breakthrough will speed up drug discovery against this disease”, explains Andrew McCarthy, one of the researchers in the team.
Scientists from the Karolinska Institute and the University of Stockholm in Sweden, together with colleagues from the European Molecular Laboratory in France have solved the three dimensional structure of the LTC4 synthase at 2.0 Ångstrom resolution . The protein has three identical subunits, each consisting of four helical structures that span the membrane. The structure finally allows the exact position and characteristics of the active sites, where activating or blocking molecules can bind, to be identified.
The study of this protein at the ESRF proved a challenge for the team. The crystallization of membrane proteins is quite a complex process and even more challenging if they are human. So far only three human membrane proteins have been structurally characterized. The team carried out experiments at the ESRF to screen crystals several times before finally being able to determine the 3D structure.
Membrane proteins- an open door to new pharmaceuticals
The new results can lead the way for the development of new and more effective medications against other diseases. Some 40 % of the proteins of interest for pharmaceutical developments are membrane proteins. (SOURCE?)
Until now detailed structural information on these proteins has been absent, and therefore it has been difficult to fully understand their function. The present study is likely to lead the way for the determination of structures of other human membrane proteins. Unravelling the secrets of more membrane protein structures will help understand fundamental processes that take place in the cell membranes.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
