Lytic transglycosylases RlpA and MltC assist in Vibrio cholerae daughter cell separation [PDF]

Molecular Microbiology, 2019
Summary The cell wall is a crucial structural feature in the vast majority of bacteria and comprises a covalently closed network of peptidoglycan (PG) strands. While PG synthesis is important for survival under many conditions, the cell wall is also a dynamic structure, undergoing degradation and remodeling by ...

Enhanced protein translocation to mammalian cells by expression of EtgA transglycosylase in a synthetic injector E. coli strain

Microbial Cell Factories, 2022
Background Bacterial type III secretion systems (T3SSs) assemble a multiprotein complex termed the injectisome, which acts as a molecular syringe for translocation of specific effector proteins into the cytoplasm of host cells.

Pseudomonas syringae lytic transglycosylase HrpH interacts with host ubiquitin ligase ATL2 to modulate plant immunity

Cell Reports
Summary: Pseudomonas syringae deploys a type III secretion system (T3SS) to deliver effector proteins to facilitate infection of plant cells; however, little is known about the direct interactions between T3SS components and plants.

A Novel Salmonella Periplasmic Protein Controlling Cell Wall Homeostasis and Virulence

Frontiers in Microbiology, 2021
Horizontal gene transfer has shaped the evolution of Salmonella enterica as pathogen. Some functions acquired by this mechanism include enzymes involved in peptidoglycan (PG) synthesis and remodeling.

Delivery determinants of an Acinetobacter baumannii type VI secretion system bifunctional peptidoglycan hydrolase

mBio
Acinetobacter baumannii is a Gram-negative opportunistic pathogen and is a common cause of nosocomial infections. The increasing development of antibiotic resistance in this organism is a global health concern. The A.

Regulation of biofilm formation in Salmonella typhimurium and Escherichia coli Nissle 1917 [PDF]

, 2011
Bacteria have the ability to grow in cell communities designated biofilms. This mode of growth is widespread and offers numerous advantages to the bacteria in terms of survival, persistence and propagation.

Image-based dynamic phenotyping reveals genetic determinants of filamentation-mediated beta-lactam tolerance [PDF]

, 2020
Antibiotic tolerance characterized by slow killing of bacteria in response to a drug can lead to treatment failure and promote the emergence of resistance.

Generation of Distinct Differentially Culturable Forms of Burkholderia following Starvation at Low Temperature

Microbiology Spectrum, 2022
Bacteria have developed unique mechanisms to adapt to environmental stresses and challenges of the immune system. Here, we report that Burkholderia pseudomallei, the causative agent of melioidosis, and its laboratory surrogate, Burkholderia thailandensis,

Reactions of All Escherichia coli Lytic Transglycosylases with Bacterial Cell Wall [PDF]

Journal of the American Chemical Society, 2013
The reactions of all seven Escherichia coli lytic transglycosylases with purified bacterial sacculus are characterized in a quantitative manner. These reactions, which initiate recycling of the bacterial cell wall, exhibit significant redundancy in the activities of these enzymes along with some complementarity.

Small Things Matter: The 11.6-kDa TraB Protein is Crucial for Antibiotic Resistance Transfer Among Enterococci

Frontiers in Molecular Biosciences, 2022
Conjugative transfer is the most important means for spreading antibiotic resistance genes. It is used by Gram-positive and Gram-negative bacteria, and archaea as well.
