Fig. 2.

Alignment of deduced amino acid sequences of the VP1 polyprotein of CV-B1 to B6 strains with their respective prototype sequence showing only the BC Loop with flanking regions. The sequences within the rectangle show variable sites within the BC-loop region. Strain designations are on the left-hand side of the alignment. Dots (.) represent amino acids identical with respect to CV-B1 to B6 prototype strain and the amino acid symbols indicate where unrelated amino acids exist with reference to prototype strain. In sequence logo the height of the logo at each site is equal to the total information at that site and the height of each symbol in the logo is proportional to its contribution to the information content.
