Figure 1
Variation of signal power (ΣS) and noise power (ΣE) in Fourier space for (a) well ordered (centre of the cytoplasmic domain) and (b) poorly ordered (chain L) regions of E. coli respiratory complex I. Both regions correspond to spheres with a radius of 30 Å. Signal power is shown with solid lines and noise power with dashed lines as it varies in three directions parallel to the x (blue), y (orange) and z (red) coordinate axes of the reconstruction. The variation of noise power is similar for the two regions of the reconstructions, but the variation of signal power differs significantly even in the relative falloff in the three directions.
