FIG. 6.

Translated nucleotide sequence of SDV 26S RNA and the extreme C terminus of nsp4. The nucleotide sequence is numbered from the 3′ end of nsp4 gene. Amino acids are numbered from the first Met capsid residue. Putative polyprotein cleavage site are indicated by bent arrows. Potential glycosylation sites are indicated by arrows. Amino acid residues with dots correspond to the transmembrane region. Underlined residues correspond to the E1 fusion domain. Asterisks indicate catalytic amino acid triad residues.
