When Thiel and colleagues 20 isolated one genomic and eight subgenomic RNAs from the FRA strain and sequenced their 5′ ends, they identified a conserved sequence (5′ACGAAC3′) that was located in coronaviruses: S, spike protein; E, envelope protein; M, membrane glycoprotein; and N, nucleocapsid protein. Alternatively, these antigens could be delivered by DNA immunization by Figure 6 | The S1 domain of SARS-CoV spike is structurally related to group 2 coronaviruses. Schematic representation of cysteine positions in the S1 domains of group 1, 2 and 3 coronaviruses, compared with the SARS-CoV spike protein. The complete genome sequence of a SARS-CoV isolate (FRA) and experimental data on its key RNA elements and protein functions are described.
