A comparative analysis of amino acid sequence of the proteins VP1 of hepatitis A virus and poliovirus of the 1 type was carried out. A model is proposed of structural organization of VP1 of hepatitis A virus providing the presence of a bilayer core formed by 8 antiparallel beta-strands. Probable candidates for surface antigenic determinants are the amino acid sequences located in unordered fragments of the polypeptide chain (residues 101-106 and 115-125), and alpha-helical region (residues 127-135).
