Figure 1. Structure comparison of rotavirus viral protein (VP) 6 proteins. A) Structure-based amino acid sequence alignment of the novel canine rotavirus VP6 protein and the template bovine rotavirus A VP6 protein. The background of the sequence alignments reflects the homology levels of the 2 VP6 sequences. Red, identical amino acid; orange, similar amino acid; pink, different amino acid). The main structural differences are indicated by dark red and menthol green on the sequence alignment and on the superimposed VP6 structures (B). Cartoon presentation of the homologous VP6 proteins: pink, rotavirus A; green, rotavirus I. Further information is available in the Technical Appendix.
