S-layer expansion during Bacillus anthracis growth is mediated by pervasive hoop-like cracks in the paracrystalline lattice, revealed by high-resolution imaging.
- Why it matters: The study addresses how the S-layer crystalline lattice expands in lockstep with dispersed peptidoglycan synthesis, a mechanism that has been unclear.
- What they did: Fluorescently labeled S-layer subunits were imaged at high resolution, and pulse-chase experiments identified two assembly modes at the cracks: dispersed and focused.
- The result: Local pulling forces linked to dispersed cell wall synthesis and peptidoglycan expansion are suggested to form cracks, enabling S-layer expansion through dispersed and focused assembly during growth.
