Trans-oligomerization of duplicated aminoacyl-tRNA synthetases maintains genetic code fidelity under stress
Aminoacyl-tRNA synthetases (aaRSs) play a key role in deciphering the genetic message by producing charged tRNAs and are equipped with proofreading mechanisms to ensure correct pairing of tRNAs with their cognate amino acid. Duplicated aaRSs are very frequent in...
O2-assisted Water Gas Shift reaction over structured Au and Pt catalyst
Platinum and gold structured catalysts were compared as active phases in classical and O2-assisted WaterGas Shift (WGS) reaction. Both metals were supported on iron-doped ceria mixed oxide and then, struc-tured on metallic micromonolithic devices. As expected the WGS...
Optofluidic Modulation of Self-Associated Nanostructural Units Forming Planar Bragg Microcavities
Bragg microcavities (BMs) formed by the successive stacking of nanocolumnar porous SiO2 and TiO2 layers with slanted, zigzag, chiral, and vertical configurations are prepared by physical vapor deposition at oblique angles while azimuthally varying the substrate...
Cytochrome c1 exhibits two binding sites for cytochrome c in plants
In plants, channeling of cytochrome c molecules between complexes III and IV has been purported to shuttle electrons within the supercomplexes instead of carrying electrons by random diffusion across the intermembrane bulk phase. However, the mode plant cytochrome c...
