Biochemistry: Combining two catalytic worlds

This is how chemical processes could become more environmentally friendly

20-Oct-2016

Chemical and biological catalysts tend to require very different reaction conditions, making their combination challenging. Researchers of the Ruhr-Universität Bochum have succeeded in taking this hurdle by using a special gel matrix to compartmentalize both types of catalysts. The results ...

Olfactory receptors discovered in bronchi

09-Aug-2016

The muscle cells of bronchi detect scents, for example a specific banana and apricot scent. This might be good news for asthma sufferers. Researchers identified two types of olfactory receptors in human muscle cells of bronchi. If those receptors are activated by binding an odorant, bronchi ...

The role played by solvents at extreme pressure

Combination of experiment and theory gives insights

04-Jul-2016

Some living organisms thrive under extraordinary conditions, such as the deep sea. But just how do they withstand the enormous pressure? Researchers at the Ruhr-Universität Bochum and the Technische Universität Dortmund have examined how the interactions between solvents and biomolecules change ...

Synthesis of hydrogen: Enzymes assemble themselves in the test tube

01-Jun-2016

Researchers from Bochum have engineered a hydrogen-producing enzyme in the test tube that works as efficiently as the original. The protein - a so-called hydrogenase from green algae - is made up of a protein scaffold and a cofactor. The latter is the reaction centre where the substances that ...

Novel optogenetic tool

Switching specific G-protein-coupled signalling pathways on and off

12-Apr-2016

Blue on, yellow off: using different-coloured light, researchers are able to switch signalling pathways in the brain on and off. Researchers in Bochum have utilised light-sensitive proteins from nerve cells of the eye – so-called melanopsins – to switch on specific signalling pathways in brain ...

Researchers use cyanobacteria for the production of chemicals

Sustainable chemical processes

01-Apr-2016

In order to manufacture chemical products in the industry, a high energy input is required, which consumes mainly our fossil resources. At RUB, two scientists are researching into a resource-efficient and, consequently, sustainable approach. Prof Dr Robert Kourist from the junior research group ...

Biomolecule’s behaviour under artificial conditions more natural than expected

Comparing cell and test tube

04-Feb-2016

Researchers often analyse isolated biomolecules in test tubes, and it is doubtful if the results can be applied to densely-packed cells. A team from Bochum, Dortmund and Greifswald monitored the folding of an RNA structure in the living cell and compared the results with those of test tube ...

Alzheimer risk impairs “satnav” function of the brain

Altered activation pattern in entorhinal cortex in young risk carriers

26-Oct-2015

Young adults with genetically increased Alzheimer’s risk have altered activation patterns in a brain region that is crucial for spatial navigation. This is reported by the team headed by Prof Nikolai Axmacher from the Ruhr-Universität Bochum, together with colleagues from the universities of ...

Protein reactions identified with subatomic resolution

08-Oct-2015

Using subatomic resolution, researchers have gained insights into the dynamic modus operandi of two switch proteins which are responsible for the import of compounds into the nucleus and for cell growth. The team headed by Prof Dr Klaus Gerwert from the Department of Biophysics at the ...

Turkish whistling makes asymmetries in the brain disappear

19-Aug-2015

Researchers at the Ruhr-Universität Bochum have debunked the theory that the left brain hemisphere is dominant in the processing of all languages. To date, it has been assumed that that dominance is not determined by the physical structure of a given language. However, the biopsychologists have ...
