WebApr 10, 2024 · The cryo-EM structure of ORF3a dimer was taken from PDB entry 7KJR as shown in Fig. 1 A [7]. Missing residues in the short loops of the ORF3a protein were modeled using the program Loopy [22]. The resulting structure was subsequently refined and further used to predict the ligand binding sites of the protein. Webmined using cryo-EM methods, an important aspect to this growth is the application of cryo-EM to determine structures of heterogeneous and dynamic assemblies. Protein …
