WebJan 25, 2024 · Cryo-EM structures of both SARS-CoV-2 and SARS-CoV-1 Orf3a display a narrow constriction and the presence of a positively-charged aqueous vestibule, which would not favor cation permeation.... 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.
