Figure 1From: NS4A protein as a marker of HCV history suggests that different HCV genotypes originally evolved from genotype 1bMultiple Sequence Alignment of NS4A protein of HCV genotype 3a. Numerical numbers at the top of the figure indicate position of the different amino acids in the NS4A protein. The isolate (genotype)/country-serial number of the sequences are shown at the left side of the figure. Dots and Roman letters in figure indicate similarity and amino acid substitutions respectively relative to the first sequence PK/FG3 taken as a reference sequence.Back to article page
