Cytosolic factors controlling PASTA kinase-dependent ReoM phosphorylation

This study identifies GpsB as an activator of PrkA, a PASTA kinase, and shows that ReoM phosphorylation is regulated by growth phase and phosphatase PrpC, with MurA's conformation and interaction with ReoM playing a key role.

Adaptation mechanisms of Listeria monocytogenes to quaternary ammonium compounds

This study identifies three adaptation mechanisms in Listeria monocytogenes to resist quaternary ammonium compounds BAC and CTAB through efflux pump overproduction, compensatory efflux systems, and membrane composition changes.

Characterization of the growth behavior of Listeria monocytogenes in Listeria synthetic media

This study examines the growth of L. monocytogenes under salt and pH stress and identifies carbon sources and genes required for growth in Listeria synthetic medium.

Imbalance of peptidoglycan biosynthesis alters the cell surface charge of Listeria monocytogenes

This study shows that EslB deficiency in Listeria monocytogenes leads to thinner peptidoglycan and increased negative surface charge, enhancing lysozyme sensitivity.

Bacillus subtilis YngB contributes to wall teichoic acid glucosylation and glycolipid formation during anaerobic growth

This study identifies YngB as a UGPase in B. subtilis that contributes to WTA glucosylation and glycolipid formation under anaerobic conditions.

The YtrBCDEF ABC transporter is involved in the control of social activities in Bacillus subtilis

This study identifies the YtrBCDEF ABC transporter as a regulator of genetic competence and biofilm formation in Bacillus subtilis by affecting cell wall properties and ComK activity.

PrkA controls peptidoglycan biosynthesis through the essential phosphorylation of ReoM

The paper identifies ReoM as a PASTA-eSTK substrate in Listeria monocytogenes, showing its phosphorylation is essential for controlling MurA degradation via ClpCP protease.

EslB is required for cell wall biosynthesis and modification in Listeria monocytogenes

This study shows that EslB, a component of the ABC transporter EslABC, is essential for cell wall biosynthesis and modification in L. monocytogenes, affecting lysozyme resistance, cell division, and growth in high-sugar media.

Phosphoglycerol-type wall- and lipoteichoic acids are enantiomeric polymers differentially cleaved by the stereospecific glycerophosphodiesterase GlpQ

This study demonstrates that WTA and LTA are enantiomeric polymers differentially cleaved by GlpQ, revealing stereochemical differences in their glycerol phosphate moieties.

GtcA is required for LTA glycosylation in Listeria monocytogenes serovar 1/2a and Bacillus subtilis

This paper shows that GtcA is essential for LTA glycosylation in L. monocytogenes and B. subtilis and suggests it functions as a C55-P-sugar flippase.

Cell shape and antibiotic resistance is maintained by the activity of multiple FtsW and RodA enzymes in Listeria monocytogenes

This study identifies multiple FtsW and RodA enzymes in Listeria monocytogenes that maintain cell shape and antibiotic resistance, with their expression regulated in response to beta-lactam antibiotics.

The cell cycle regulator GpsB functions as cytosolic adaptor for multiple cell wall enzymes

This study identifies GpsB as a cytosolic adaptor that coordinates cell wall synthesis with the bacterial cell cycle by interacting with multiple enzymes and proteins.
