Fig. 3. Spatial organization of proteins in a partial β-carboxysome from the 30% fraction. (A) High-resolution AFM topograph of a partial β-carboxysome fragment in buffer. (B) High-pass-filtered AFM image showing the protein organization in the shell fragment depicted in (A). The white line of the cross section was used to calculate the pattern of hexamer organization in (C). (C) The cross-section profile illustrates the periodic arrangement of hexamers and the center-to-center distance between neighboring hexamers is ∼9 nm. (D) Three-dimensional height image of the shell showing the shell protein structures and arrangement.
