Intramembrane signal transduction and cell envelope stress response in <i>Bacillus subtilis</i>
… für ein Bakterium lebenswichtig. Die Zellhüllstress-Antwort in Bacillus subtilis wird durch sieben signaltransduzierende Systeme vermittelt, zu denen drei ECF-sigma-Faktoren und vier Zweikomponentensysteme gehören. Eines dieser Zweikomponentensysteme ist das LiaRS-System, welches auf …

A role for a predicted E. coli inner membrane lipoprotein in cell envelope integrity
… is the possession of a double-membraned cell envelope. The outer membrane provides an additional layer of protection against hydrophobic molecules including antibiotics, contributing to the multidrug resistance crisis. The Gram-negative membrane is composed of phospholipids, glycolipids, and …

Analysis of a bacterial serine/threonine kinase
… of cell surface appendages and is one of three envelope stress response systems, it is hypothesized that RdoA serves to relay Cpx activation signals. This is supported by studies on the effect of pH on Cpx activity in wildtype and rdoA- cells presented here. RdoA homologues are present in at …

Investigation of Bacillus subtilis Sigma Factor Dynamics Using Improved Single Cell Tools
… activation. Here, we investigate the single cell response dynamics of the \textit{B. subtilis} extracytoplasmic function sigma factors, which are an important part of the cell envelope stress response, under their specific stresses. To do this we use transcriptional reporters of sigma factors, …

Structure and function analysis of the natural product plantazolicin, a bacillus anthracis-specific antibiotic
… upregulation of genes within the cell envelope stress response. Using fluorescence microscopy, PZN localizes to distinct ~200 nm wide foci within the envelope; furthermore, like other cell envelope-acting compounds, PZN depolarizes the B. anthracis membrane. Upon selection and …

Conformational Rearrangements In The Sensory Rcsf/Omp Complex Mediate Signal Transduction Across The Bacterial Cell Envelope
<p>Timely detection and repair of envelope damage are paramount for bacterial survival. The Regulator of Capsule Synthesis (Rcs) stress response is a complex signaling cascade that monitors gram-negative cell envelope integrity and can transduce the stress signals across the multilayered envelope …

Surface Localization Determinants of Borrelia burgdorferi Lipoproteins
… lipoprotein that influences sorting within the envelope. One facet of this study utilized an N-proximal tandem negative charge (Glu-Asp) that served as an inner membrane retention signal in OspA20:mRFP1 as a target for mutagenesis. A library of random mutants in the two codons was generated and …
