The ClpX chaperone modulates assembly of the tubulin‐like protein FtsZ [PDF]

Molecular Microbiology, 2005
SummaryAssembly of the tubulin‐like cytoskeletal protein FtsZ into a ring structure establishes the location of the nascent division site in prokaryotes. Factors that modulate FtsZ assembly are essential for ensuring the precise spatial and temporal regulation of cytokinesis.

Physiological and transcriptomic evidence for a close coupling between chloroplast ontogeny and cell cycle progression in the pennate diatom Seminavis robusta [PDF]

, 2008
Despite the growing interest in diatom genomics, detailed time series of gene expression in relation to key cellular processes are still lacking. Here, we investigated the relationships between the cell cycle and chloroplast development in the pennate ...

A Uniform Benchmark for Testing SsrA-Derived Degrons in the Escherichia coli ClpXP Degradation Pathway

Molecules, 2021
The ssrA degron is commonly used in fusion proteins to control protein stability in bacteria or as an interaction module. These applications often rely on the modular activities of the ssrA tag in binding to the SspB adaptor and in engaging the ClpXP ...

Degradation of a Caulobacter Soluble Cytoplasmic Chemoreceptor Is ClpX Dependent [PDF]

Journal of Bacteriology, 2002
ABSTRACT In order to determine whether ClpXP-mediated proteolysis is a common mechanism used to regulate the chemotaxis machinery during the cell cycle of Caulobacter crescentus , we have characterized a soluble cytoplasmic chemoreceptor, McpB.

Snow stratigraphic heterogeneity within ground-based passive microwave radiometer footprints: implications for emission modeling [PDF]

, 2014
Two-dimensional measurements of snowpack properties (stratigraphic layering, density, grain size and temperature) were used as inputs to the multi-layer Helsinki University of Technology (HUT) microwave emission model at a centimeter-scale horizontal ...

Subunit asymmetry and roles of conformational switching in the hexameric AAA+ ring of ClpX [PDF]

, 2015
The hexameric AAA+ ring of Escherichia coli ClpX, an ATP-dependent machine for protein unfolding and translocation, functions with the ClpP peptidase to degrade target substrates.

The Bacterial ClpXP-ClpB Family Is Enriched with RNA-Binding Protein Complexes

Cells, 2022
In the matrix of bacteria/mitochondria/chloroplasts, Lon acts as the degradation machine for soluble proteins. In stress periods, however, proteostasis and survival depend on the strongly conserved Clp/Hsp100 family. Currently, the targets of ATP-powered

Engineering an Optogenetic pH‐Modulator in Bacteria

Advanced Science, EarlyView.
ABSTRACT Cells in many naturally occurring organisms routinely cooperate to control their extracellular pH in a dynamic and reversible manner, but this capability has been underexplored in synthetic biology. Here, we sought to engineer a microbial system that switches between two states —high and low extracellular pH— with minimal human intervention ...

ClgR regulation of chaperone and protease systems is essential for Mycobacterium tuberculosis parasitism of the macrophage [PDF]

, 2010
Chaperone and protease systems play essential roles in cellular homeostasis and have vital functions in controlling the abundance of specific cellular proteins involved in processes such as transcription, replication, metabolism and virulence.

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.
