The deduced amino acid sequence comparison and hydrophobicity profiles of the gp3 proteins between the 7 isolates and reference viruses. A, deduced amino acid sequence comparison of the gp3 proteins between the 7 isolates from China (GenBank accession no. EU017511, EU177104, EU177109, EU177118, EU255923, EU366149 and EU439254) and another Chinese isolates (BJ-4) (GenBank accession no. AF331831), VR2332 (GenBank accession no. EF536003) and MLV (GenBank accession no. AF159149) available in GenBank. Only the amino acids different from those in the consensus sequence are indicated. The black boxed residues indicate the difference AA position sites. B, Hydrophobicity plots of ORF3 generated by the Kyte and Doolittle method using by DNAstar program. Major areas of difference are indicated by arrows. a, GC-2 was a representative of other three isolates because the same plots were shown for GCH-3, HQ-5 and HQ-6. b, LS-4 was a representative of other two isolates because the same plots were shown for LS-4 and ST-7. c, VR2332 was a representative of other two reference virus because the same plots were shown for VR2332, BJ-4 and MLV.
