Overview

Observational analysis shows separate roles of SEDS-bPBP and class A PBPs in septal synthesis, implying conserved mechanisms.

Key Points

  • Septal peptidoglycan synthesis is driven primarily by SEDS-bPBP pairs during early constriction.
  • Class A PBPs reinforce septal integrity later, enhancing cross-linking and wall thickness.
  • Synthesis occurs at distinct sites in space and time, showcasing a coordinated mechanism.
  • Spatiotemporal separation of synthases was observed in both Deinococcus radiodurans and Staphylococcus aureus.
