Bacterial two-component systems (TCSs) often function through the detection of an extracytoplasmic stimulus and transduction a signal by transmembrane sensory histidine kinase. This kinase then initiates series reversible phosphorylation modifications to regulate activity cognate, cytoplasmic response regulator as transcription factor. Several TCSs have been implicated in regulation cell cycle dynamics, envelope integrity, or wall development Escherichia coli other well-studied Gram-negative...
The history of euglenoids may have begun as early ~2 bya. These phagotrophs ate cyanobacteria, archaea, and eubacteria, the subsequent appearance red algae chromalveolates provided with additional food sources. Following green algae, acquired a chloroplast via secondary endosymbiotic event algal ancestor. This endosymbiosis also involved massive transfer nuclear‐encoded genes from symbiont nucleus to host. Expecting these origin, this research has shown, through use DNA ‐sequences analysis...
Cell elongation and division are essential aspects of the bacterial life cycle that must be coordinated for viability replication. The impact misregulation these processes is not well understood as systems often amenable to traditional genetic manipulation. Recently, we reported on CenKR two-component system (TCS) in Gram-negative bacterium Rhodobacter sphaeroides genetically tractable, widely conserved α-proteobacteria, directly regulates expression components crucial cell division,...
ABSTRACT The bacterial cell envelope is a key subcellular compartment with important roles in antibiotic resistance, nutrient acquisition, and morphology. We seek to gain better understanding of proteins that contribute the function Alphaproteobacteria . Using Rhodobacter sphaeroides , we show previously uncharacterized protein, RSP_1200, an outer membrane (OM) lipoprotein non-covalently binds peptidoglycan (PG). fluorescently tagged version this find RSP_1200 undergoes dynamic repositioning...
