Extended Data Fig. 4. CryoEM analysis of the MERS-CoV S glycoprotein in complex with Neu5Gc at 3.0 Å resolution.
a,b, Representative electron micrograph (a) and class averages (b) for the Neu5Gc-bound MERS-CoV S structure. c, Gold-standard Fourier shell correlation curve. The 0.143 cut-off is indicated by horizontal dashed lines. d, Representative density shown as blue mesh with the corresponding atomic model rendered as sticks colored grey, blue and red for carbon, nitrogen and oxygen atoms, respectively.
