Interactions between CsgG and CsgF monomers in the CsgG-CsgF complex. (a) Residues in a CsgF monomer form hydrogen bonds with residues in three CsgG monomers. Hydrogen bonds are marked by dashed lines between interacting atoms (distance of < 0.32 nm). (b) Electrostatic interactions between CsgF Arg-8 and CsgG Asp-149 and Glu-185 residues. The bond distance is plotted for nine monomers over 100 ns simulation in 0.075 V nm⁻¹.
