Schematic representation showing the structure of the vector constructs and pre-S1 promoter sequence. a A schematic diagram showing the structure of the pre-S1 promoter and the wild type (WT), G2765A (m5), and whole nucleotide mutation (m9) nucleotide sequences of the Sp1 region. b Alignment of the pre-S1 promoter nucleotide sequences, including the consensus sequence, representative references, and substitution strains. Nucleotide symbol R indicates A (adenine) or G (guanine)
