  1. Note: the nucleotides conserved with respect to the reference sequence were marked with a dash (.), whereas a variation position was indicated by a letter. The “S” in the last row of the table means Strand, the “H” means Helix. The “AA” means amino acid. The “R, E, F, T, K, Y” in the seventh and ninth rows of the table represent arginine, glutamic acid, phenylalanine, threonine, lysine and tyrosine, respectively. The numbers in the second row of the table mean nucleotide positions
