Fig. 5: Variability of filament pairing.
From: The hierarchical assembly of septins revealed by high-speed AFM
a Septin filament pairing exhibit subunit interaction match and mismatch in the same field of investigation. b Periodicity length distribution of interacting elements peaking at ~32 nm, i.e., the length of the hetero-octameric septin rod. High-resolution images of c matched and d mismatched filament pairs. Bottom in c and d: Structural models of matched and mismatched rod interactions. The HS-AFM resolution does not allow to distinguish the precise nature of the septin subunit, cases where Cdc10 (label 10) and/or Cdc11 (label 11) face each other are illustrated. e Histogram analysis of the top-to-top distance of the filaments in filament-pairs peaking at ~4 nm.
