(Submitter supplied) Quorum sensing is a term used to describe cell-to-cell communication that allows cell density-dependent gene expression. Many Gram-negative bacteria use acyl-homoserine lactone (acyl-HSL) synthases to generate fatty acyl-HSL quorum sensing signals, which function with signal receptors to control expression of specific genes. The fatty acyl group is derived from fatty acid biosynthesis and provides signal specificity, but the variety of signals is limited. more...

(Submitter supplied) To address the question of how photosynthetic bacterium Rhodopseudomonas palustris metabolize lignin derived compound p-coumarate, transcriptomics and quantitative proteomics were combined to characterize gene expression profiles at both the mRNA level and protein level in Rhodopseudomonas palustris grown with succinate, benzoate, and p-coumarate as the carbon source.

(Submitter supplied) Photosynthetic microbes can produce the clean-burning fuel hydrogen using one of nature’s most plentiful resources, sunlight 1,2. Anoxygenic photosynthetic bacteria generate hydrogen and ammonia during a process known as biological nitrogen fixation. This reaction is catalyzed by the enzyme nitrogenase and consumes nitrogen gas, ATP and electrons 3. One bacterium, Rhodopseudomonas palustris, has a remarkable ability to obtain electrons from green plant-derived material 4,5 and to efficiently absorb both high and low intensity light energy to form ATP 6. more...
