Folds and activities of peptidoglycan amidases [PDF]

FEMS Microbiology Reviews, 2007
Bacterial peptidoglycan amidases are a large and diverse group of enzymes. During the last few years, genomic sequence information has accumulated to an extent such that lists of proven or predicted peptidoglycan amidases can now be expected to be fairly complete.

The PECACE domain: a new family of enzymes with potential peptidoglycan cleavage activity in Gram-positive bacteria

BMC Genomics, 2005
Background The metabolism of bacterial peptidoglycan is a dynamic process, synthases and cleavage enzymes are functionally coordinated. Lytic Transglycosylase enzymes (LT) are part of multienzyme complexes which regulate bacterial division and elongation.

Structural basis for the hydrolytic activity of the transpeptidase-like protein DpaA to detach Braun’s lipoprotein from peptidoglycan

mBio, 2023
The peptidoglycan layer is a defining characteristic of bacterial cells, providing them with structural support and osmotic protection. In Escherichia coli, this layer is linked to the outer membrane via the abundant membrane-anchored protein Lpp, known ...

Peptidoglycan synthesis drives FtsZ treadmilling-independent step of cytokinesis

Nature, 2018
Peptidoglycan is the main component of the bacterial wall and protects cells from the mechanical stress that results from high intracellular turgor.

Peptidoglycan recognition in innate immunity [PDF]

Journal of Endotoxin Research, 2005
The innate immune system recognizes micro-organisms through a series of pattern recognition receptors that are highly conserved in evolution. Peptidoglycan (PGN) is a unique and essential component of the cell wall of virtually all bacteria, is not present in eukaryotes, and is an excellent target for the innate immune system.

Protein O‐glycosylation in the Bacteroidota phylum

FEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

Peptidoglycan-type analysis of the N-acetylmuramic acid auxotrophic oral pathogen Tannerella forsythia and reclassification of the peptidoglycan-type of Porphyromonas gingivalis

BMC Microbiology, 2019
Background Tannerella forsythia is a Gram-negative oral pathogen. Together with Porphyromonas gingivalis and Treponema denticola it constitutes the “red complex” of bacteria, which is crucially associated with periodontitis, an inflammatory disease of ...

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]

, 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.

Peptidoglycan Remodeling Enables Escherichia coli To Survive Severe Outer Membrane Assembly Defect

mBio, 2019
In Gram-negative bacteria, the outer membrane protects the cell against many toxic molecules, and the peptidoglycan layer provides protection against osmotic challenges, allowing bacterial cells to survive in changing environments.
