Figure 3From: First construction of infectious clone for newly emerging mutation porcine circovirus type 2 (PCV2) followed by comparison with PCV2a and PCV2b genotypes in biological characteristics in vitroSequence alignment of the deduced amino acid (aa) sequences of the capsid proteins (encoded by ORF2) of the four cloned strains of PCV2. Mutations at the C terminus of the capsid protein in the four rescued viruses are shown, resulting in elongation of the ORF2 by one lysine residue (for PCV2d/rBDH) or asparagine and glutamic acid residue (for PCV2b/rYJ), compared with the wild-type sequence (red box).Back to article page
