Activity Control of the ClpC Adaptor McsB in Bacillus subtilis [PDF]
ABSTRACT Controlled protein degradation is an important cellular reaction for the fast and efficient adaptation of bacteria to ever-changing environmental conditions. In the low-GC, Gram-positive model organism Bacillus subtilis , the AAA+ protein ClpC requires specific adaptor proteins not only for ...

Functional Analysis of the Hsp93/ClpC Chaperone at the Chloroplast Envelope [PDF]
The Hsp100-type chaperone Hsp93/ClpC has crucial roles in chloroplast biogenesis. In addition to its role in proteolysis in the stroma, biochemical and genetic evidence led to the hypothesis that this chaperone collaborates with the inner envelope TIC complex to power preprotein import.

Ring-forming AAA+ chaperones exert ATP-fueled substrate unfolding by threading through a central pore. This activity is potentially harmful requiring mechanisms for tight repression and substrate-specific activation.

ClpC acts as a negative regulator of competence in Streptococcus thermophilus [PDF]
The alternative sigma factor ComX is a key regulator of natural transformation in members of the genus Streptococcus. ComX controls expression of the late competence genes, which are essential for DNA binding, uptake and recombination. In Streptococcus pneumoniae, it has been demonstrated that ComX is degraded by ClpEP at the end of the competence ...

Isolation of highly heat-resistant Listeria monocytogenes variants by use of a kinetic modeling-based sampling scheme [PDF]
Stable high-hydrostatic-pressure (HHP)-resistant Listeria monocytogenes LO28 variants were previously isolated and characterized. These HHP variants were also more resistant to heat.

The Bacillus subtilis clpC operon encodes DNA repair and competence proteins [PDF]
ClpC of Bacillus subtilis, controlling competence gene expression and survival under stress conditions, is encoded by the fourth gene of a six-gene operon. The product of orf1 contains a potential helix-turn-helix motif, but shows no significant similarities with known protein sequences.

A MecA Paralog, YpbH, Binds ClpC, Affecting both Competence and Sporulation [PDF]
ABSTRACT ComK, the master regulator of competence, is degraded by the general stress-related protease ClpCP but must be targeted to this protease by binding to the adapter protein MecA. The genome of Bacillus subtilis contains a paralog of mecA , ypbH .
