The amino-acid sequence of the four WNV strains is compared with the WNV consensus sequence. From the left, the first and second columns display viral protein and amino-acid position, respectively, followed by the column displaying the consensus sequence and those corresponding to each WNV strain. The amino-acid residue occupying each position is indicated with the single letter amino-acid code.
