Two New M23 Peptidoglycan Hydrolases With Distinct Net Charge

Frontiers in Microbiology, 2021
Bacterial peptidoglycan hydrolases play an essential role in cell wall metabolism during bacterial growth, division, and elongation (autolysins) or in the elimination of closely related species from the same ecological niche (bacteriocins).

Dual glycosylation of wall teichoic acid modulates the O-antigen pattern and virulence in serovar 4b <i>Listeria monocytogenes</i>. [PDF]

mLife
Abstract Among the 14 serovars of Listeria monocytogenes (Lm), serovar 4b strains are the most predominant isolates linked to human listeriosis outbreaks‐a phenotype associated with their unique wall teichoic acid (WTA) decorated with galactose (Gal) and glucose (Glu).

Triosephosphate isomerase of Streptococcus pneumoniae is released extracellularly by autolysis and binds to host plasminogen to promote its activation

FEBS Open Bio, 2022
Recruitment of plasminogen is an important infection strategy of the human pathogen Streptococcus pneumoniae to invade host tissues. In Streptococcus aureus, triosephosphate isomerase (TPI) has been reported to bind plasminogen. In this study, the TPI of

Design of a novel affinity probe using the cell wall-binding domain of a Listeria monocytogenes autolysin for pathogen detection

Microbiology Spectrum, 2023
Rapid identification of foods and food-processing environments contaminated with Listeria monocytogenes is crucial for controlling human listeriosis, a leading cause of fatality related to foodborne illnesses. The L.

The Pneumococcal Protein SufC Binds to Host Plasminogen and Promotes Its Conversion into Plasmin

Microorganisms, 2023
Streptococcus pneumoniae causes otitis media, sinusitis, and serious diseases such as pneumonia and bacteremia. However, the in vivo dynamics of S. pneumoniae infections and disease severity are not fully understood.

Staphylococcus aureus Cell Wall Biosynthesis Modulates Bone Invasion and Osteomyelitis Pathogenesis

Frontiers in Microbiology, 2021
Staphylococcus aureus invasion of the osteocyte lacuno-canalicular network (OLCN) is a novel mechanism of bacterial persistence and immune evasion in chronic osteomyelitis. Previous work highlighted S.

Contribution of autolysin to virulence of Streptococcus pneumoniae [PDF]

Infection and Immunity, 1989
Insertion-duplication mutagenesis was used to construct an autolysin-negative derivative of Streptococcus pneumoniae. This derivative was obtained by first transforming the nonencapsulated strain Rx1 with a derivative of the vector pVA891 carrying a 375-base-pair TaqI DNA fragment from the middle of the autolysin structural gene. DNA was extracted from
