Secondary structure of HPV-33 E6 comparing reference to the variant sequence. Note a is the secondary structure pattern diagram constructed based on HPV-33 E6 reference sequence; a is the secondary structure pattern diagram constructed based on HPV-33 E6 mutation sequence. The black boxes are the difference areas between the reference and mutation sequence secondary structure
