Staphylococcus aureus ClpC Is Required for Stress Resistance, Aconitase Activity, Growth Recovery, and Death [PDF]

Journal of Bacteriology, 2005
ABSTRACT The ability of Staphylococcus aureus to adapt to various conditions of stress is the result of a complex regulatory response. Previously, it has been demonstrated that Clp homologues are important for a variety of stress conditions, and our laboratory has shown that

Functional Interaction Between Toc75 POTRA1 Domain and Tic22‐III in the Intermembrane Space During Chloroplast Protein Import

Plant Direct, Volume 10, Issue 2, February 2026.
ABSTRACT Chaperones are essential for facilitating the import of nuclear‐encoded precursor proteins into chloroplasts. In the intermembrane space (IMS) of the chloroplasts, this process is mediated by the transport‐associated domains (POTRA) of the translocon at the outer envelope membrane (Toc75) and translocon at the inner envelope membrane (Tic22 ...

Characterization of relationships between transcriptional units and operon structures in and [PDF]

, 2007
Background Operon structures play an important role in transcriptional regulation in prokaryotes. However, there have been fewer studies on complicated operon structures in which the transcriptional units vary with changing environmental conditions ...

Symbiont Gene Expression Predicts Insect Host's Response to High Temperatures

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Microbial symbionts play crucial roles in host nutrition, defence, and detoxification. However, host‐symbiont interactions are context‐dependent, and environmental stressors can disrupt these benefits. Diverse hosts, including corals, insects and leguminous plants, have been shown to suffer under thermal stress due to the negative impact of ...

The Involvement of the McsB Arginine Kinase in Clp-Dependent Degradation of the MgsR Regulator in Bacillus subtilis

Frontiers in Microbiology, 2020
Regulated ATP-dependent proteolysis is a common feature of developmental processes and plays also a crucial role during environmental perturbations such as stress and starvation.

Glucose Uncouples Nitrogen Sensing From Chlorosis via a Photosynthetic Checkpoint in Synechocystis sp. PCC 6803

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Cyanobacteria adapt to nitrogen starvation by undergoing chlorosis, a regulated bleaching process that involves the degradation of phycobilisomes, the light‐harvesting antennae complexes, and accumulation of glycogen. While this response is well characterized under photoautotrophic conditions, its modulation by external organic carbon sources ...

ClpC and MecA, components of a proteolytic machine, prevent Spo0A‐P‐dependent transcription without degradation [PDF]

Molecular Microbiology, 2018
SummaryIn Bacillus subtilis, a proteolytic machine composed of MecA, ClpC and ClpP degrades the transcription factor ComK, controlling its accumulation during growth. MecA also inhibits sporulation and biofilm formation by down‐regulating spoIIG and sinI, genes that are dependent for their transcription on the phosphorylated protein Spo0A‐P ...

Adaptive Tolerance of Listeria monocytogenes to Chemical Oxidants: Comparative Analysis of Transcriptomic Studies

Comprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 5, September 2025.
ABSTRACT Listeria monocytogenes is a foodborne pathogen that poses significant challenges to food safety and public health due to its ability to adapt to harsh environments, particularly those found in food processing facilities. This review explores the global transcriptional responses of L.
