Fig. 3. Cryo-EM single-particle reconstruction of the MTBD-High-MT complex in the absence (−) and presence (+) of DTT.

Fig. 3

a Fourier Shell Correlation (FSCtrue) curves for the structures of MTBD-High-MT complex for both ± DTT conditions, using a FSC 0.143 criterion. b, c Cryo-EM density segmented from the post-processed maps (using relion_postprocess, filtered to local resolution) of MTBD-High-MT complex and fitted atomic model of H4, H7, GMPCPP, and Mg2+ of α-tubulin (PDB code: 1JFF) for (b) DTT(−) and (c) DTT(+) conditions. d, e C1 reconstruction of MTBD-High-MT complex for (d) DTT(−) and (e) DTT(+) conditions (filtered to 4.44 Å and 4.33 Å, respectively). The broken line indicates the location of the seam. The upper half is displayed at high threshold to show secondary structures in MTs. The lower half is displayed at lower threshold to show the MTBD structure. f, g Density of MTBD-High-MT complex colored and filtered according to local resolution determined using relion_postprocess for (f) DTT(−) and (g) DTT(+) conditions.
