Comparative nucleotide sequence analysis of the phosphoprotein gene of peste des petits ruminants vaccine virus of Indian origin.

The nucleotide sequences of the phosphoprotein (P) gone of peste des petits ruminants (PPRV) vaccine virus (PPRV Sungri/96) belongs to Asian lineage have been determined and the deduced amino acid sequences were compared with another vaccine strain PPRV/Nigeria75/l and with those of the other morbilliviruses. The 1652 nucleotides of the P gone encode a phosphoprotein of 509 amino acid residues (from nucleotide numbers 60 to 1587), which is 91% identical to that of PPRV/Nigeria75/l. The C protein consists of 177 amino acid residues and is 91% identical with that of PPRV/Nigeria75/l. The conserved mRNA editing site (5′TTAAAAGGGCACAG) was present at positions 742-756 in the P gone, which is conserved in all other morbilliviruses, The CTT trinucleotide sequence is present at the N/P and P/M intergenic region, which is totally conserved in morbilliviruses. This will be the third sequence for the P gone of PPRV since that of the vaccine strain and a wild-type Turkish isolate has been published already. [ABSTRACT FROM AUTHOR]
