ABSTRACT
A complementary DNA copy of DEN-1 RNA was synthesized using reverse transcriptase and a random primer. The double-stranded DNA copy was cloned at the Sma I site of the pUC13 vector and was used to transform Escherichia coli JM83. Among the transformants selected for characterization by nucleotide sequence analysis, we report here one that codes for a region of nonstructural hydrophilic protein, NS-3. Computer analysis of this sequence (967 bp) showed abouth 87% conservation at the amino acid level and 79% at the nucleotide level when compared with dengue serotypess 2,3 and 4 and Japanese encephalitis virus. This suggest an important function which is common to all four serotypes. Comparision of the cloned region with sequences of the above strains also suggest conservation of hydrophobic regions
