Discovery and Characterization of Iron Sulfide and Polyphosphate Bodies Coexisting in Archaeoglobus fulgidus Cells

Figure 2

CryoET of A. fulgidus cells reveals dense cytoplasmic bodies. (a) Central slice from a 3D tomogram reconstructed from a cryoET tilt series of a whole cell frozen in vitreous ice. (b) The two granules present in (a) are enlarged to show their amorphous features. The Fourier transform of each granule is shown on the right. (c) Central slice from the 3D tomogram of another cell. (d) 3D rendering of the cell in (c) shown from different angles. The cell is shown in pink, the 2 granules are shown in blue and yellow, and the dimensions of the cell are indicated.
