Identification and characterization of genotype A and D recombinant hepatitis B virus from Indian chronic HBV isolates

Figure 3 Recombinant sequence similarities with genotype A in PreS2 and Surface region. A: Surface region alignment with genotype A and D amino acids, marked in red shows all three recombinant sequences having similarity with genotype A, whereas yellow marked amino acids shows at least one recombinant sequence similar to genotype A, over all 18 positions; B: Shows same in the preS2 region; C: Shows all the amino acids of MHR of genotype D in black, upward arrow indicates the change of amino acid; D: Shows “a” determinant region and corresponding alignment with 12 isolates.
