Molecular imaging of glycan chains couples cell-wall polysaccharide architecture to bacterial cell [PDF]
Biopolymer composite cell walls maintain cell shape and resist forces in plants, fungi and bacteria. Peptidoglycan, a crucial antibiotic target and immunomodulator, performs this role in bacteria.

In vitro destruction of Streptococcus pneumoniae biofilms with bacterial and phage peptidoglycan hydrolases. [PDF]
ABSTRACTHost- and phage-coded cell wall hydrolases have been used to fightStreptococcus pneumoniaegrowing as planktonic cellsin vitroas well as in animal models. Until now, however, the usefulness of these enzymes in biofilm-grown pneumococci has gone untested. The antipneumococcal activity of different cell wall hydrolases produced byS.

Detection and Localization of a Peptidoglycan Hydrolase in Lactobacillus delbrueckiisubsp. bulgaricus [PDF]
Peptidoglycan hydrolase activities in Lactobacillus delbrueckii subsp. bulgaricus were detected by analysis of bacterial extracts on denaturing polyacrylamide gel electrophoresis containing lyophilized Micrococcus lysodeikticus cells as substrate. A hydrolase with an estimated molecular mass of 80 kDa was found to cross-react on Western blot with ...

Bacteriophage virion-associated peptidoglycan hydrolases: potential new enzybiotics [PDF]
Virion-associated peptidoglycan hydrolases (VAPGH) are phage-encoded lytic enzymes that locally degrade the peptidoglycan (PG) of the bacterial cell wall during infection. In contrast to endolysins, PGHs that mediate lysis of the host bacteria at the end of the lytic cycle to release of phage progeny, the action of VAPGHs generates a small hole through

Bacterial SH3 (SH3b) domains are commonly fused with papain-like Nlp/P60 cell wall hydrolase domains. To understand how the modular architecture of SH3b and NlpC/P60 affects the activity of the catalytic domain, three putative NlpC/P60 cell wall ...

A Proteolytic Complex Targets Multiple Cell Wall Hydrolases in
Carboxy-terminal processing proteases (CTPs) occur in all three domains of life. In bacteria, some of them have been associated with virulence. However, the precise roles of bacterial CTPs are poorly understood, and few direct proteolytic substrates have

Most bacteria are surrounded by their cell wall, containing a highly cross-linked protective envelope of peptidoglycan. To grow, bacteria must continuously remodel their wall, inserting new material and breaking old bonds.

Reduced peptidoglycan synthesis capacity impairs growth of E. coli at high salt concentration
Gram-negative bacteria have a thin peptidoglycan layer between the cytoplasmic and outer membranes protecting the cell from osmotic challenges. Hydrolases of this structure are needed to cleave bonds to allow the newly synthesized peptidoglycan strands ...

Bacterial cells are encased in a peptidoglycan (PG) exoskeleton that protects them from osmotic lysis and specifies their distinct shapes. Cell wall hydrolases are required to enlarge this covalently closed macromolecule during growth, but how these ...
