Architecture is key: Biomolecule metal–organic hybrids with high bioactivity
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 ...
Discovery could lead to more environmental protection in the chemical industry
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 ...
Several billion-year-old enzymes resurrected and a completely new non-natural reaction catalysed
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 ...
Polystyrene waste to break down with enzymes or bacteria?
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, ...
Scientists found a method for the "green" production of the important starting material for the chemical industry
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 ...
Researchers identify enzyme which becomes catalytically active by light
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 ...
Future applications primarily in the production of active pharmaceutical ingredients, but also in the synthesis of fine chemicals expected
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 ...
How cyanobacteria can be transformed into hydrogen factories
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 ...
Triple-stranded molecule may help put chemistry's holy grail in reach
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 ...
A research team has developed a new method to drive catalytically active enzymes
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 ...
