Protein structure analysis and modeling of VP7 from Venezuelan rotavirus G1P[8] strains. The protein structure of VP7 from three Venezuelan G1P[8] strains from Caracas isolated during the season 2007/2008 (blue) (represented as just one, because identical among them) has been superimposed to the VP7 protein structure of Rotarix® vaccine strain (gray). The model was built using the UCSF Chimera-Molecular Modeling System v1.11 [37]. Surface-exposed residues that differ between the VP7 protein from Venezuelan 2007/2008 RV strains and the Rotarix® vaccine strain are indicated
