Figure 5. . . Sequence alignments of the amino acid sequences of human adenovirus (HAdV) 40 long fiber (fiber 2) with simian adenovirus (SAdV) 18 fiber (upper lines) and HAdV-40 short fiber (fiber 1) with macaque adenovirus isolate A1173 (lower lines). Gray shading indicates homologous regions, red font indicates identical residues, underlining indicates N-terminal 30 residues that constitute the tail, and boxes indicate C-terminal knob domains. Intervening shaft domains harboring varying numbers of the ≈16-residue β-spiral repeat sequences are separated by asterisks and numbered sequentially.
