Making better use of enzymes

New research project at Jacobs University

20-Sep-2018

In biocatalysis, enzymes are used to accelerate chemical reactions. This plays a role in many areas, such as the production of beer, wine and cheese or the pharmaceutical industry. A research project at the English-medium Jacobs University led by Marcelo Fernandez-Lahore, Professor of Biochemical ...

Newly discovered enzyme is 'firing pin' for plant immunity

19-Sep-2018

Just like humans, plants have an immune system that helps them fight off infections. Plant immunity has some important differences: they don't make antibodies and can't fight off the same bug more quickly months or years later. However, plant cells can identify pathogens and react to them, often ...

Two new ways to fluorinated structures

Chemo-enzymatic synthesis of fluorinated antibiotics

07-Aug-2018

Fluorinated structures make up more than 20 percent of modern drugs, but benign and fast fluorination schemes are scarce. In a study scientists have now combined dynamic kinetic resolution and nucleophilic fluorination for the asymmetric synthesis of florfenicol, a veterinary antibiotic. After ...

Low-cost plastic sensors could monitor a range of health conditions

27-Jun-2018

An international team of researchers have developed a low-cost sensor made from semiconducting plastic that can be used to diagnose or monitor a wide range of health conditions, such as surgical complications or neurodegenerative diseases. The sensor can measure the amount of critical ...

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 ...
