Abstract
The sequence of the 5′-end of the genome of dengue 2 (Jamaica genotype) virus has been previously reported (V. Deubel, R. M. Kinney, and D. W. Trent, 1986, Virology 155, 365-377). We have now cloned and sequenced the remaining 75% of the genomic RNA that encodes the nonstructural proteins. The complete genome is 10,723 bases in length with a single open reading frame extending from nucleotides 97 to 10,269 encoding 3391 amino acids. The 3′-noncoding extremity presents a stem- and loop-structure and contains a repeated oligonucleotide sequence. Comparisons of the nucleotide sequences of the genomes of dengue 2 viruses of different topotypes reveal 90-95% similarity, with 64-66% similarity evident between dengue viruses of different serotypes. The amino acid sequence of the polyprotein of dengue 2 Jamaica virus shows 97, 68, 50, and 44% similarity with those of other dengue 2, dengue 1, or dengue 4, West Nile, and yellow fever viruses, respectively. Despite amino acid sequence divergence, the hydrophobic profile of the flavivirus proteins is highly conserved. Proteins NS1, NS3, and NS5 are the most conserved. Conserved amino acid stretches present in all flavivirus proteins may be involved in common essential biological functions.
