Enigma of fatty acid metabolism solved

Enzyme shape controls its activity

15-Jun-2018

Fats are essential for our body. The core components of all fats are fatty acids. Their production is initiated by the enzyme ACC. Researchers at the University of Basel’s Biozentrum have now demonstrated how ACC assembles into distinct filaments. As the researchers report in “Nature,” the type ...

Self-sustaining loop of chemical reactions could revolutionize drug production

07-Jun-2018

Experts from the University of Nottingham have created a self-sustaining circuit of reactions which is a greener and more efficient method of chemical production. Drs Francesca Paradisi and Martina Contente of the University of Nottingham produce chemicals more efficiently through a looped set of ...

Designer cells: artificial enzyme can activate a gene switch

A new kind of chemistry in living organisms

24-May-2018

Complex reaction cascades can be triggered in artificial molecular systems: Swiss scientists have constructed an enzyme than can penetrate a mammalian cell and accelerate the release of a hormone. This then activates a gene switch that triggers the creation of a fluorescent protein. The findings ...

New 'NanoZymes' use light to kill bacteria

Artificial enzymes could be used in hospitals and toilets

06-Apr-2018

Researchers from RMIT University have developed a new artificial enzyme that uses light to kill bacteria. The artificial enzymes could one day be used in the fight against infections, and to keep high-risk public spaces like hospitals free of bacteria like E. coli and Golden Staph. E. coli can ...

Photosynthetic microalgae as biocatalysts

The biocatalytic production of chemicals should become considerably more sustainable

06-Mar-2018

A carpet of blue-green algae can literally ‘cloud’ the summer’s swimming pleasure at the lake. This is caused by a few strains of photosynthetically active microalgae, also known as cyanobacteria. Other harmless strains of cyanobacteria have great potential for biotechnological applications and ...

Plastic bags that cannot breathe

Optimized enzyme variant can degrade plastic under anaerobic conditions

05-Mar-2018

Many bio-plastic bags have no place in the garbage. They dissolve too slowly in oxygen-deficient environments like biogas plants and when incinerated they are a burden to the environment. A research project at the Austrian Centre of industrial Biotechnology (acib) hunts for enzymes, which ...

Going with the DNA flow: Molecule of life finds new uses in microelectronics

28-Feb-2018

For sheer versatility, there's no molecule quite like DNA. The iconic double-helix carries the genetic blueprint for living forms ranging from single-celled organisms to human beings. Recently, researchers have found that DNA's remarkable properties of self-assembly and its ability to conduct ...

Sticking sugar to protein

Researchers clarified the 3D structure of an important enzyme that links sugar to proteins – a breakthrough

09-Feb-2018

Whenever cells receive signals, interact with other cells or identify viruses and bacteria, the process involves not only proteins but also sugar chains attached to their surface. The subject of relatively little attention until now, these structures differ widely in composition and branching, ...

New insights into how your brain keeps its balance

23-Jan-2018

As with all things in life, healthy brain function depends on a balance of forces. We think of our brains as active - moving a leg and saying a word are all "active" events. But it is just as important for our brains to be able to stop these actions -to stop our leg, and to stop our speech. But ...
