Versatility and multifunctionality of highly reflecting Bragg mirrors based on nanoparticle multilayers
The use of both supported and flexible self-standing nanoparticle-based one dimensional photonic crystal films as effective frequency selective filters in the UV-vis-NIR is herein evaluated. The requirements to achieve a flat spectral response at the desired frequency...
Nitration of tyrosine 74 prevents human cytochrome c to play a key role in apoptosis signaling by blocking caspase-9 activation
Tyrosine nitration is one of the most common post-transcriptional modifications of proteins, so affecting their structure and function. Human cytochrome c, with five tyrosine residues, is an excellent case study as it is a well-known protein playing a double...
Organocatalytic Asymmetric Cyanosilylation of Nitroalkenes
A new catalyst type for a new reaction. The unprecedented cyanosilylation of nitroalkenes can be efficiently catalyzed by a bifunctional quinine derivative bearing tetra-alkylammonium cyanide and thiourea moieties. The activation of the nitroalkene by H-bonding to the...
Inhibition of Target of Rapamycin signaling and stress activate autophagy in Chlamydomonas reinhardtii
Autophagy is a catabolic membrane-trafficking process whereby cells recycle cytosolic proteins and organelles under stress conditions or during development. This degradative process is mediated by autophagy-related (ATG) proteins which have been described in yeasts,...
Fra proteins influencing filament integrity, diazotrophy and localization of septal protein SepJ in the heterocyst-forming cyanobacterium Anabaena sp.
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that can fix N2 in differentiated cells called heterocysts, which exchange nutritional and regulatory compounds with the neighbouring photosynthetic vegetative cells. The cells in the filament appear to be...
