*Monomeric units found in the interface. [AB] type interface is formed between two units from two stacked pentameric rings or [AC] type interface forms between two units within the same ring (see Fig. 4).

^†Change in free energy associated with the assembly dissociation (ΔG^{diss >} 0 means the assembly is thermodynamically stable). Slashes indicate that this assembly is not recommended by PISA.

^‡Complexation Significance Scores (CSS) are from 0 to 1 in which 1 indicates the most probable interface for a stable assembly.
