P and V mutant proteins. (Top) Schematic drawing illustrating the open reading frames of the P and V proteins (from the top). (Bottom) Sequence alignments of amino acids 81 to 150 in the shared segment of six Morbilliviruses P and V proteins. Gene bank numbers for each sequence are: AAF85668.1 (MV), CAA48389.1 (Rinderpest virus [RV]), AAQ96296.1 (canine distemper virus [CDV]), BAA01203.1 (phocine distemper virus [PV]), CAH61253.1 (Peste des petits ruminants [PPR]), and CAE55654.1 (dolphin morbillivirus [DV]). Sequence alignments were performed at the Swiss Institute of Bioinformatics using the BLAST network service, NCBI BLAST 2 software (3) and the CLUSTAL W program. The Yrich sequence is boxed. *, Residues identical in all sequences; “:” and “.”, conservative and semiconservative substitutions, respectively. Introduced amino acid mutations are indicated above the sequences.
