Optimization of ClpXP activity and protein synthesis in an E. coli extract-based cell-free expression system [PDF]
Protein degradation is a fundamental process in all living cells and is essential to remove both damaged proteins and intact proteins that are no longer needed by the cell.

Role of Hsp100/Clp protease complexes in controlling the regulation of motility in Bacillus subtilis [PDF]
The Hsp100/Clp protease complexes of Bacillus subtilis ClpXP and ClpCP are involved in the control of many interconnected developmental and stress response regulatory networks, including competence, redox stress response and motility.

The ClpXP protease and the ClpX unfoldase control virulence, cell division, and autolysis in Streptococcus pneumoniae [PDF]
In all living cells, molecular chaperones and ATP-dependent proteases are essential for protein homeostasis. The ClpXP protease is a chaperone-protease complex conserved between bacteria and mitochondria.

NOA1, a novel ClpXP substrate, takes an unexpected nuclear detour prior to mitochondrial import. [PDF]
The mitochondrial matrix GTPase NOA1 is a nuclear encoded protein, essential for mitochondrial protein synthesis, oxidative phosphorylation and ATP production. Here, we demonstrate that newly translated NOA1 protein is imported into the nucleus, where it

A new regulator of the Staphylococcus aureus peptidoglycan hydrolase Sle1. [PDF]
Regulation of peptidoglycan hydrolases is crucial for bacterial cell integrity, growth and division. In the bacterial pathogen Staphylococcus aureus, the amidase Sle1 is a key autolysin required for septum splitting and daughter cell separation.

Temperature-dependent regulation of bacterial cell division hydrolases by the coordinated action of a regulatory RNA and the ClpXP protease [PDF]
A defining feature of bacteria is the peptidoglycan cell wall which provides structural integrity and prevents osmotic lysis. While peptidoglycan hydrolases are required for daughter cell separation, dysregulated cell wall degradation may result in cell ...

Utilizing nanoinducers for precision degradation of bacterial protein to mitigate antibiotic resistance [PDF]
Antibiotic resistance stands as a formidable global challenge to public health. Herein, we present a bacterial nanoinducer (bacNID) designed for targeted protein degradation in treating bacterial infections. Specifically, bacNID is engineered by grafting

A proteolytic AAA+ machine poised to unfold protein substrates [PDF]
AAA+ proteolytic machines unfold proteins before degrading them. Here, we present cryoEM structures of ClpXP-substrate complexes that reveal a postulated but heretofore unseen intermediate in substrate unfolding/degradation. A ClpX hexamer draws natively
