A study conducted by teams from LOB, BIAM Cadarache and I2BC, combining multiple techniques including ADASOPS multi-scale transient infrared absorption spectroscopy, shows that, contrary to previous assumptions, at physiological temperature CO₂ is converted into an intermediate other than bicarbonate in the catalytic mechanism of FAP, a natural photoenzyme showing great promise for applications in green chemistry. This work was published in ACS...

Researchers from LOB Ecole Polytechnique and CEA Cadarache uncover the ultrafast photooxidation dynamics of the flavin cofactor in the natural photoenzyme - fatty acid photodecarboxylase (FAP). Using femtosecond transient absorption spectroscopy, the team demonstrates that photoexcitation of the flavin anion radical triggers its oxidation to FAD within only 100 femtoseconds. Remarkably, the process involves the transient formation of a hydrated...

Researchers from the Laboratory for Optics and Biosciences participated in a study showing that certain three-dimensional structures of DNA, known as G-quadruplexes, play a key role in regulating gene expression in mammals. This work was published in Nature Genetics . For more information
