Figure 5. In vitro polymerization of MamK and MamK-like visualized by TEM.

Sizes of structures are indicated with arrows. Structures narrower than 10 nm are termed “filaments” and larger structures are termed “bundles”. A–B) MamK polymers. C–D) MamK-like polymers. Scale bars: 100 nm in A, B and D; 300 nm in C.
