Fig. 2From: Genetic characterization and phylogeny of pigeon paramyxovirus isolate (PPMV-1) from PakistanAlignment of deduced amino acid sequence of complete F gene of pigeon isolate. The residue profile of study isolate is compared with strains of NDVs representing different genotypes including the vaccine strains. Structurally and functionally important residues are boxed and highlighted Back to article page
