In the behavior known as quorum sensing (QS), bacteria release diffusible signal molecules known as autoinducers, which by accumulating in the environment induce population-wide changes in gene expression. Although QS has been extensively studied in well-mixed systems, the ability of diffusing QS signals to synchronize gene expression in spatially extended colonies is not well understood. Here ...

Here, we describe the draft genome sequence of Vibrio fischeri SR5, a squid symbiotic isolate from Sepiola robusta in the Mediterranean Sea. This 4.3-Mbp genome sequence represents the first V. fischeri genome from an S. robusta symbiont and the first from outside the Pacific Ocean.

Two syntheses of natural viridic acid, an unusual triply N-methylated peptide with two anthranilate units, are presented. The first one is based on peptide-coupling strategies and affords the optically active natural product in 20% overall yield over six steps. A more economical approach with only four steps leads to the similarly active racemate by utilizing a Ugi four-component reaction (Ugi-...

conclusions the obtained results revealed that there has been a high rate of genetic diversity in bioluminescent strains isolated from gulf of izmir and v. lentus and v. crassostreae strains could be also bioluminescent for the first report. at the same time, pfge analysis of bioluminescent bacteria including four different genera and ten different species were shown for the first time by this ...

The psychrophilic and mesophilic endonucleases A (EndA) from Aliivibrio salmonicida (VsEndA) and Vibrio cholera (VcEndA) have been studied experimentally in terms of the biophysical properties related to thermal adaptation. The analyses of their static X-ray structures was no sufficient to rationalize the determinants of their adaptive traits at the molecular level. Thus, we used Molecular Dyna...
