Structures of accessory proteins. ad Overall structure of ORF3a, ORF7a, ORF8, and ORF 9b, respectively. e Structure of ORF9b in complex with human protein TOM70, a subunit of the mitochondrial import receptor. ORF9b is shown as yellow cartoon. TOM70 is illustrated with electrostatic surface on the right. The ORF9b binds to the hydrophobic pocket of TOM70 and occupies its binding site
