Mechanisms Controlling the Cell Envelope Remodeling Activities of the Escherichia Coli Cytokinetic Ring
In Escherichia coli, cytokinesis requires the constriction of all the cell envelope layers: the inner membrane, the peptidoglycan (PG) cell wall and the outer membrane (OM). Such dramatic cell envelope remodeling requires ...
Fitness Tradeoffs, Bimodality, and the Genetics of Natural Variation in Glucose-Galactose Sensing Across Saccharomyces Cerevisiae
In nature, cells must constantly sense their environment and respond appropriately. These cellular “decisions” are implemented by molecular components that can mutate and evolve. How do mutations lead to changes in cellular ...
A sigma factor and anti-sigma factor that control swarming motility and biofilm formation in Pseudomonas aeruginosa
Pseudomonas aeruginosa is an environmental bacterium and opportunistic human pathogen of major clinical significance. It is the principal cause of morbidity and mortality in patients with cystic fibrosis (CF) and a leading ...
