A secreted bacterial peptidoglycan hydrolase enhances tolerance to enteric pathogens [PDF]
The intestinal microbiome modulates host susceptibility to enteric pathogens, but the specific protective factors and mechanisms of individual bacterial species are not fully characterized. We show that secreted antigen A (SagA) from Enterococcus faecium is sufficient to protect Caenorhabditis elegans

Encapsulation of the septal cell wall protects Streptococcus pneumoniae from its major peptidoglycan hydrolase and host defenses. [PDF]
Synthesis of the capsular polysaccharide, a major virulence factor for many pathogenic bacteria, is required for bacterial survival within the infected host.

Structure of the Large Extracellular Loop of FtsX and Its Interaction with the Essential Peptidoglycan Hydrolase PcsB in
Streptococcus pneumoniae is a leading killer of infants and immunocompromised adults and has become increasingly resistant to major antibiotics. Therefore, the development of new antibiotic strategies is desperately needed.

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.

Identification of the chain-dispersing peptidoglycan hydrolase LytB of Streptococcus gordonii. [PDF]
Bacterial cell division ends with the separation of the daughter cells, a process that requires peptidoglycan hydrolases (PGHs). Bacteria lacking cell separating PGHs are impaired in cell separation with the formation of long chains or clusters.

Enterococcus faecium sagA mutants have cell envelope defects influencing antibiotic resistance and bacteriophage susceptibility [PDF]
Enterococcus faecium is a gram-positive bacterium that is resident to the intestines of animals including humans. E. faecium is also an opportunistic pathogen that causes multidrug-resistant (MDR) infections. Bacteriophages (phages) have been proposed as
