Drosophila immunity: analysis of PGRP-SB1 expression, enzymatic activity and function.
PLoS ONE, 2011 Peptidoglycan is an essential and specific component of the bacterial cell wall and therefore is an ideal recognition signature for the immune system. Peptidoglycan recognition proteins (PGRPs) are conserved from insects to mammals and able to bind PGN ...

Towards an Ontological Representation of Resistance: The Case of MRSa [PDF]
, 2009 This paper addresses a family of issues surrounding the biological phenomenon of resistance and its representation in realist ontologies. Resistance terms from various existing ontologies are examined and found to be either overly narrow, inconsistent ...

Nature Microbiology, 2019 Bacteria are protected by a polymer of peptidoglycan that serves as an exoskeleton1. In Staphylococcus aureus, the peptidoglycan assembly enzymes relocate during the cell cycle from the periphery, where they are active during growth, to the division site

Advanced Science, EarlyView.An integral functional axis through which GPN and functional metabolites of Alistipes senegalensis can hydrolyze tryptophan into indoles. Furthermore, the Alistipes senegalensis‐indole‐AhR pathway is found to be associated with increased expression of tight junction‐associated proteins and activation of gut stem cells.

Genetic Evidence for Distinct Functions of Peptidoglycan Endopeptidases in Escherichia coli
Frontiers in Microbiology, 2020 Peptidoglycan (PG) is an essential component of the bacterial exoskeleton that plays a pivotal role in the maintenance of cell shape and resistance to cell lysis under high turgor pressures.

Kytococcus aerolatus sp. nov., isolated from indoor air in a room colonized with moulds [PDF]
, 2009 A Gram-positive, coccoid bacterial isolate (02-St-019/1(T)), forming beige pigmented colonies was obtained from an indoor air sample. Based on 16S rRNA gene sequence similarity studies it was determined that this isolate 02-St-019/1(T) belonged to the ...

Structural bases of peptidoglycan recognition by lysostaphin SH3b domain
Scientific Reports, 2019 Staphylococcus simulans lysostaphin cleaves pentaglycine cross-bridges between stem peptides in the peptidoglycan of susceptible staphylococci, including S. aureus.

Advanced Science, EarlyView.In the tripartite‐species model, Drosophila larvae stimulate lactate production through excreting digestion enzymes. S. marcescens population senses a cue of lactate and tends to diverge into virulent and reduced virulence subclusters with remarkable heterogeneity to metabolize carbon metabolism and counter colonization resistance, giving a fitness ...

Anchoring of Surface Proteins to the Cell Wall of Staphylococcus aureus: sortase catalyzed in vitro transpeptidation reaction using LPXTG peptide and NH2-Gly3 substrates [PDF]
, 2000 Staphylococcus aureus sortase anchors surface proteins to the cell wall envelope by cleaving polypeptides at the LPXTG motif. Surface proteins are linked to the peptidoglycan by an amide bond between the C-terminal carboxyl and the amino group of the ...
