Well shielded but highly active

Architecture is key: Biomolecule metal–organic hybrids with high bioactivity

03-Jul-2020

Biomacromolecules incorporated into tailored metal–organic frameworks using peptide modulators are well shielded but highly active thanks to carefully tuned nanoarchitecture. As scientists report in the journal Angewandte Chemie, this strategy can be used to synthesize an “artificial cell” that ...

Algae as living biocatalysts for a green industry

Discovery could lead to more environmental protection in the chemical industry

03-Jul-2020

Many substances that we use every day only work in the right 3D structure. Natural enzymes could produce these in an environmentally friendly way – if they didn’t need a co-substrate that is expensive to produce to date. A research team at Ruhr-Universität Bochum (RUB) has discovered exactly the ...

Ancient enzymes can contribute to greener chemistry

Several billion-year-old enzymes resurrected and a completely new non-natural reaction catalysed

15-Jun-2020

A research team at Uppsala University has resurrected several billion-year-old enzymes and reprogrammed them to catalyse completely different chemical reactions than their modern versions can manage. The method can be used to develop sustainable solutions within biotechnology, such as for enzyme ...

Superworms digest plastic, with help from their bacterial sidekicks

Polystyrene waste to break down with enzymes or bacteria?

02-Jun-2020

Resembling giant mealworms, superworms (Zophobas atratus) are beetle larvae that are often sold in pet stores as feed for reptiles, fish and birds. In addition to their relatively large size (about 2 inches long), these worms have another superpower: They can degrade polystyrene plastic. Now, ...

Environmentally friendly production of mandelic acid

Scientists found a method for the "green" production of the important starting material for the chemical industry

29-May-2020

Sometimes potentially useful enzymes are not easy to discover because their biocatalytic capabilities may go beyond their natural and thus known range of action. By recombining a newly discovered enzymatic capability, a research team from the Max Planck Institute for Terrestrial Microbiology led ...

Triggered by light, a novel way to switch on an enzyme

Researchers identify enzyme which becomes catalytically active by light

28-May-2020

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme ...

On our way to the bio-economy: High-performance biocatalyst discovered

Future applications primarily in the production of active pharmaceutical ingredients, but also in the synthesis of fine chemicals expected

22-May-2020

In the bioeconomy, biotechnological processes are replacing processes that rely on fossil resources. Microorganisms and enzymes are being used in targeted fashion as biocatalysts for industrial production. Researchers at the University of Bayreuth have now discovered an enzyme that offers great ...

Energy of the future: photosynthetic hydrogen from bacteria

How cyanobacteria can be transformed into hydrogen factories

06-May-2020

The transition from fossil fuels to a renewable energy supply is one of the most important global challenges of the 21st century. In order to achieve the internationally-agreed target of limiting global warming to a maximum of 1.5 degrees, the international community must drastically reduce ...

Chemists create new artificial enzyme

Triple-stranded molecule may help put chemistry's holy grail in reach

12-Mar-2020

Enzymes are nature's powerhouses. Found in the cells of all animals, plants, and every other living organism, they accelerate the chemical reactions that trigger thousands of biological functions--from forming neurons to digesting food. They perform their jobs so selectively and so ...

Plasma-driven biocatalysis

A research team has developed a new method to drive catalytically active enzymes

04-Mar-2020

Compared with traditional chemical methods, enzyme catalysis has numerous advantages. But it also has weaknesses. Some enzymes are not very stable. Enzymes that convert hydrogen peroxide are even inactivated by high concentrations of the substrate. A research team at Ruhr-Universität Bochum ...
