Yichang virus genome organization and structural proteins.

Schematic diagram of the organization of Yichang virus genome. Open reading frames (ORFs) are shown by boxes, with nucleotide positions indicated. Conserved domains are highlighted in colors. (b) SDS-PAGE analysis of the proteins for Yichang virus. Specific ORFs shown to encode the respective proteins are given on the right, together with the predicted molecular masses. Predicted N-linked glycosylation sites in the S and M proteins are indicated by triangles. (c) Transmembrane domains, signalase cleavage site and furin-like proteases cleavage site in the precursor ORF2a polypeptide. (d) Transmembrane domains and signalase cleavage site of precursor ORF3a polypeptide.
