A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

open access: yesAdvanced Science, EarlyView.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

Mycobacterium tuberculosis FtsX extracellular domain activates the peptidoglycan hydrolase, RipC [PDF]

open access: yesProceedings of the National Academy of Sciences, 2014
Significance During growth and division, bacterial cells partition the cell wall to daughter cells, but the “inside-out” signals that regulate peptidoglycan (PG) hydrolysis are not well understood. Our studies of mycobacterial proteins achieve in vitro reconstitution of the regulation of the PG hydrolase, RipC, by the FtsX extracellular ...

Comprehensive and Comparative Transcriptional Profiling of the Cell Wall Stress Response in Bacillus subtilis

open access: yesMolecular Microbiology, EarlyView.
Transcriptional profiling of the primary cell envelope stress response (CESR) of Bacillus subtilis exposed to a range of cell wall‐targeting antimicrobials, combining RNAseq and high‐resolution tiling arrays. We revealed the complexity of the CESR, the contribution of extracytoplasmic function sigma factors (ECFs) and two‐component signal transduction ...

Staphylococcus aureus cell wall structure and dynamics during host-pathogen interaction.

open access: yesPLoS Pathogens, 2021
Peptidoglycan is the major structural component of the Staphylococcus aureus cell wall, in which it maintains cellular integrity, is the interface with the host, and its synthesis is targeted by some of the most crucial antibiotics developed.

Identification of a New Family of Enzymes with Potential \u3cem\u3eO\u3c/em\u3e-acetylpeptidoglycan esterase activity in both Gram-positive and Gram-negative bacteria [PDF]

open access: yes, 2005
Background: The metabolism of the rigid bacterial cell wall heteropolymer peptidoglycan is a dynamic process requiring continuous biosynthesis and maintenance involving the coordination of both lytic and synthetic enzymes.

Structural and biochemical characterization of the exopolysaccharide deacetylase Agd3 required for Aspergillus fumigatus biofilm formation [PDF]

open access: yes, 2020
The exopolysaccharide galactosaminogalactan (GAG) is an important virulence factor of the fungal pathogen Aspergillus fumigatus. Deletion of a gene encoding a putative deacetylase, Agd3, leads to defects in GAG deacetylation, biofilm formation, and ...

Histiocytes: Multifaceted Regulators of Health and Disease

open access: yesVeterinary Clinical Pathology, EarlyView.
ABSTRACT The mononuclear phagocyte system encompasses macrophages, dendritic cells (DCs), and monocytes. Tissue‐resident macrophages and dendritic cells arise during embryogenesis and are replenished either through self‐renewal or by monocytes during inflammation.

O-Glycosylation as a Novel Control Mechanism of Peptidoglycan Hydrolase Activity [PDF]

open access: yesJournal of Biological Chemistry, 2013
Acm2, the major autolysin of Lactobacillus plantarum, is a tripartite protein. Its catalytic domain is surrounded by an O-glycosylated N-terminal region rich in Ala, Ser, and Thr (AST domain), which is of low complexity and unknown function, and a C-terminal region composed of five SH3b peptidoglycan (PG) binding domains.

Phage-derived peptidoglycan degrading enzymes: challenges and future prospects for in vivo therapy [PDF]

open access: yes, 2018
Peptidoglycan degrading enzymes are of increasing interest as antibacterial agents, especially against multi-drug resistant pathogens. Herein we present a review about the biological features of virion-associated lysins and endolysins, phage-derived ...
