Extended Data Fig. 8: Intact monocins produced by the Δ15-mttP mutant.

A TEM image of stained free monocin particles produced by L. monocytogenes 10403 S bacteria expressing the Δ15-MttP mutated protein, treated with MMC. Bacterial lysates were filtered through 0.22 μm filters, and the monocin particles were further precipitated using PEG-8000. A representative image is shown.
