The molecular structure and shape of CDP-ME kinase
The shape of the CDP-ME kinase active site with location of substrates.
A European team of scientists from the University of Dundee (UK), the Technical University of Munich (Germany) and the European Synchrotron Radiation Facility, ESRF, (France) have determined the structure of a key target enzyme for novel drug development to treat infectious diseases including malaria, tuberculosis and sexually transmitted bacterial infections. The results of their collaboration are published on the August 5 issue of Proceedings of the National Academy of Sciences.
Synchrotron radiation at the ESRF played a key role in the determination of the structure of the enzyme CDP-ME kinase. The experiment took place on one of the macromolecular crystallography beamlines at the ESRF. This kinase helps to produce many of the molecules that bacteria and parasites need to live and multiply. A molecule that can prevent the kinase from working normally will poison and kill the pathogenic organisms.
The determination of the structure of the enzyme provides a template for the design of small molecules that will inhibit its action and prevent it from working normally. In the future, the structure may help lead to the development of new potent therapies for a wide range of microbial infections. “These drugs could potentially help the treatment of not only malaria and tuberculosis but also toxoplasmosis, chlamydia, meningitis and cholera for example”, explains Professor Bill Hunter, one of the authors of the article.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
