Cysteine-mediated mechanism disrupts energy transfer to prevent photooxidation.

Unlike higher plants, which are often awash in sunlight, green sulfur bacteria survive in some of the darkest and most inhospitable environments for photosynthetic organisms. From the bottom of the Black Sea to the underside of thick microbial mats growing atop hot springs, these anaerobic archaea subsist on the rare photons that penetrate into their dark environments. For this reason, it is su...

Synthetic Fatty Acids Prevent Plasmid-Mediated Horizontal Gene Transfer

UNLABELLED Bacterial conjugation constitutes a major horizontal gene transfer mechanism for the dissemination of antibiotic resistance genes among human pathogens. Antibiotic resistance spread could be halted or diminished by molecules that interfere with the conjugation process. In this work, synthetic 2-alkynoic fatty acids were identified as a novel class of conjugation inhibitors. Their che...

Breather-mediated Energy Transfer in Proteins

In this paper we investigate how energy is redistributed across protein structures, following localized kicks, within the framework of a nonlinear network model. We show that energy is directed most of the times to a few specific sites, systematically within the stiffest regions. This effect is sharpened as the energy of the kicks is increased, with fractions of transferred energy as high as 70...

Energy Transfer Mechanism in Gd2(Si04)0:Ce Scintillators

The scintillation decay of cerium-doped gadolinium oxyorthosilicate Gd2(Si04)0:Ce is lengthened by the energy transfer from Gd to Ce. To investigate the role of the Gd in the scintillation processes, the Gd was partially replaced by optically inactive rare earth elements, Y and Lu, and the effective transfer rates from Gd to Ce were measured as a function of Gd and Ce concentrations using UVand...
