Osmosensing by bacteria: signals and membrane-based sensors

Article Abstract:

The use of osmosensors offers substantial benefits to biological studies, particularly in analyzing various solvent-membrane and solvent-macromolecule interactions. By tracking down changes in solvent osmolality and their impact on cell structure, osmosensors allow users to identify water activity and cosolvent specificity. These devices are particularly functional in determining collective changes in the intracellular concentration of chemically induced cosolvents.

Cyclopropane ring formation in membrane lipids of bacteria

Article Abstract:

Gram-positive and gram-negative bacterial genera are known to produce cyclopropane fatty acids (CFAs). However there are complicating factors in the synthesis of CFAs, such as its dependence on physiological conditions. CFA formation is therefore considered a conditional, postsynthetic modification of bacterial membrane lipid bilayers. Topologically novel protein-lipid interactions occur in CFA biosynthesis.

Programmed death in bacteria

Article Abstract:

Programmed cell death appears to occur in many bacteria and protozoa. It functions primarily as a means of eliminating defective cells. This mechanism appears to be disabled in persistent cells that are resistant to killing.
