Secondary structure of HPV-16 E6 comparing reference to the variant sequence. Note a is the secondary structure pattern diagram constructed based on HPV-16 E6 reference sequence; b is the secondary structure pattern diagram constructed based on HPV-16 E6-1 mutation sequence; c is the secondary structure pattern diagram constructed based on HPV-16 E6-2 mutation sequence, b and c are different in 32th amino acid. The black boxes are the difference areas between the reference and mutation sequence secondary structure.
