Green chemistry and biofuel: the mechanism of a key photoenzyme decrypted


Green chemistry and biofuel: the mechanism of a key photoenzyme decrypted
08-04-2021
The functioning of the enzyme FAP, useful for producing biofuels and for green chemistry, has been decrypted. This result mobilized an international team of scientists, including many French researchers from the CEA, CNRS, Inserm, École Polytechnique, the universities of Grenoble Alpes, Paris-Saclay and Aix Marseille, as well as the European Synchrotron (ESRF) and synchrotron SOLEIL. The study is published in Science on April 09, 2021.

The researchers decrypted the operating mechanisms of FAP (Fatty Acid Photodecarboxylase), which is naturally present in microscopic algae such as Chlorella. The enzyme had been identified in 2017 as able to use light energy to form hydrocarbons from fatty acids produced by these microalgae. To achieve this new result, research teams used a complete experimental and theoretical toolkit. ....

NTU scientists design new compound that could help reduce overactive immune response


NTU scientists design new compound that could help reduce overactive immune response
When the body detects a pathogen, such as bacteria or viruses, it mounts an immune system response to fight this invader. In some people, the immune system overreacts, resulting in an overactive immune response that causes the body to injure itself, which may prove fatal in some cases.
Now, scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a compound that could help to reduce this overactivation without impairing the body s entire immune response.
An overactive immune system leads to many autoimmune disorders - when the immune system mistakenly attacks healthy tissues - such as rheumatoid arthritis and type 1 diabetes. More recently, it has also been linked to severe COVID-19 infections, in which immune-system signalling proteins ramp up to dangerous levels, leading to damage to the body s own cells. ....
