Archaea produce peptidoglycan hydrolases that kill bacteria [PDF]
PLoS BiologyThe social life of archaea is poorly understood. In particular, even though competition and conflict are common themes in microbial communities, there is scant evidence documenting antagonistic interactions between archaea and their abundant prokaryotic brethren: bacteria. Do archaea specifically target bacteria for destruction? If

Peptidoglycan Hydrolases of Escherichia coli [PDF]
Microbiology and Molecular Biology Reviews, 2011 SUMMARYThe review summarizes the abundant information on the 35 identified peptidoglycan (PG) hydrolases ofEscherichia coliclassified into 12 distinct families, including mainly glycosidases, peptidases, and amidases. An attempt is also made to critically assess their functions in PG maturation, turnover, elongation, septation, and recycling as well as

Peptidoglycan hydrolases-potential weapons against Staphylococcus aureus [PDF]
Applied Microbiology and Biotechnology, 2012 Bacteria of the genus Staphylococcus are common pathogens responsible for a broad spectrum of human and animal infections and belong to the most important etiological factors causing food poisoning. Because of rapid increase in the prevalence of isolation of staphylococci resistant to many antibiotics, there is an urgent need for the development of new

Prediction of peptidoglycan hydrolases- a new class of antibacterial proteins [PDF]
BMC Genomics, 2016 The efficacy of antibiotics against bacterial infections is decreasing due to the development of resistance in bacteria, and thus, there is a need to search for potential alternatives to antibiotics. In this scenario, peptidoglycan hydrolases can be used as alternate antibacterial agents due to their unique property of cleaving peptidoglycan cell wall ...

False positives in using the zymogram assay for identification of peptidoglycan hydrolases [PDF]
Analytical Biochemistry, 2018 Zymogram assays have been used extensively to identify novel peptidoglycan hydrolases. In this study it is reported that the zymogram is susceptible to false positive results when highly positively charged proteins are assayed. As an example, we report on the case of the ChiZ membrane protein from the Mycobacterium tuberculosis divisome, which ...

Coordinated peptidoglycan synthases and hydrolases stabilize the bacterial cell wall
Nature Communications, 2023 Peptidoglycan (PG) defines cell shape and protects bacteria against osmotic stress. The growth and integrity of PG require coordinated actions between synthases that insert new PG strands and hydrolases that generate openings to allow the insertion ...

Identification of the chain-dispersing peptidoglycan hydrolase LytB of Streptococcus gordonii. [PDF]
PLoS ONE, 2017 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.

Regulation of peptidoglycan hydrolases: localization, abundance, and activity. [PDF]
Curr Opin Microbiol, 2023 Most bacteria are surrounded by a cell wall composed of peptidoglycan (PG) that specifies shape and protects the cell from osmotic rupture. Growth, division, and morphogenesis are intimately linked to the synthesis of this exoskeleton but also its hydrolysis. The enzymes that cleave the PG meshwork require careful control to prevent aberrant hydrolysis

Bacterial peptidoglycan (murein) hydrolases [PDF]
FEMS Microbiology Reviews, 2008 Most bacteria have multiple peptidoglycan hydrolases capable of cleaving covalent bonds in peptidoglycan sacculi or its fragments. An overview of the different classes of peptidoglycan hydrolases and their cleavage sites is provided. The physiological functions of these enzymes include the regulation of cell wall growth, the turnover of peptidoglycan ...

Recent Advances in Peptidoglycan Synthesis and Regulation in Bacteria
Biomolecules, 2023 Bacteria must synthesize their cell wall and membrane during their cell cycle, with peptidoglycan being the primary component of the cell wall in most bacteria.
