a
nt, nucleotide sequence position in the SI-1 B viral genome; aa, predicted coding length of the respective gene product.
b
Percentages are based on comparisons of total number of aligned amino acids; numbers in parentheses represent actual alignments. Genomic comparisons are based on global genome-to-genome alignment. no. AF033817, unknown viral origin; AF042071, German isolate RKI-3; D13784, ATL isolate of Caribbean origin; J02029, ATL isolate of Japanese origin.
