Mild extraction preserves labile structural features of Gram-positive bacterial cell wall glycopolymers

This paper introduces a mild extraction method for Gram-positive bacterial cell wall glycopolymers that preserves structural integrity and yields 17 distinct glycopolymers from 11 species.

Exploring the antimicrobial potential of streptococcal fratricins

This study evaluates the antimicrobial activity of three streptococcal fratricins, finding Zoocin A has broad target range and activity against caries-associated and pathogenic species.

Cyclic di-AMP signalling affects cell division and penicillin susceptibility in Streptococcus pneumoniae.

This study shows cyclic di-AMP affects cell division and penicillin susceptibility in Streptococcus pneumoniae by regulating division machinery and cell wall composition.

LytF contributes to pilus extrusion during natural competence in Streptococcus sanguinis SK36.

This study shows that LytF promotes pilus extrusion in Streptococcus sanguinis, enhancing DNA uptake during natural transformation, contrary to previous speculation that it functions as a fratricin.

The effect of MurM and a branched cell wall structure on penicillin resistance in Streptococcus pneumoniae

This study investigates the role of MurM and branched cell wall structures in penicillin resistance in Streptococcus pneumoniae, finding no direct correlation between increased branching and resistance.

Self-immunity towards a novel competence-induced streptococcal murein hydrolase is mediated by a Fem-transferase-like protein

The paper identifies ScrM, a competence-induced murein hydrolase in Streptococcus dysgalactiae, and shows that ScrI, a Fem-transferase-like protein, mediates self-immunity by modifying peptiglycan to prevent ScrM binding.
