E2 DNA Binding Domain Protein Alignment. Amino acid sequences for all known E2 proteins were acquired from NCBI and aligned using Muscle. (a) This figure shows the sequence alignment of the Alpha-papillomavirus C-terminal 80 amino acids of the E2 DNA binding domain. The colors represent homologous amino acids and the bar-graphs below represent a quantitative measure of conservation at each position. (b) This figure shows the sequence alignment of the Beta-papillomavirus C-terminal 80 amino acids of the E2 DNA binding domain.
