The four final maps are labeled AD, and shown with all the resolutions and particle numbers. Maps C and D had been utilized for model creating.

Single particle cryo-EM analysis of Hrd1/Hrd3 complexes.a, Density maps had been generated for the Hrd1/Hrd3 dimer, the Hrd1 dimer with a single connected Hrd3 molecule, the Hrd1 dimer, and Hrd3 (see Extended Information Fig. 2). The left panels show the maps in a side view, colored based on nearby resolution, the middle panels show the gold-standard Fourier shell correlation (FSC) curve (blue) with indicated resolutionNature. Author manuscript; obtainable in PMC 2018 January 06.Schoebel et al.Pageat FSC = 0.143, plus the ideal panels show the Euler angle distribution in two different views. Inside the two decrease panels, the dashed grey FCS curves have been calculated in between the atomic model and also the corresponding final cryo-EM map. b, The density map for the Hrd1/Hrd3 dimer was filtered to a resolution of 6.8without amplitude modification, and is displayed at two various isosurface levels. At a low level (left panel), the weak amphipol density is visible and encloses the density of Hrd1 dimer. The amphipathic helix of Hrd3 only associates with all the outer surface of amphipol density. At a higher isosurface level (middle and suitable panels), the density for the amphipathic helix is clearly connected with that on the preceding Sel1 domains and well separated from that of TM1 and TM2 from the nearby Hrd1 molecule.
