This paper investigates the role of teichoic acids in maintaining the periplasmic space in Streptococcus pneumoniae using cryo-electron microscopy and metabolic labeling, revealing new insights into TA composition and function.

The paper shows that MapZ in Streptococcus pneumoniae identifies the division site by recognizing a specific peptidoglycan composition formed during early cell division, independent of chromosome segregation.

This paper investigates DivIVA's role in Streptococcus pneumoniae cell division and elongation using microscopy and modeling, revealing its control over septum cleavage and peptidoglycan synthesis.
