Fig. 1

Structure of the RAdV-1 fibre head domain and comparison with the TAdV-3 fibre head. a The RAdV-1 fibre head monomer. Beta-strands are labelled (except the J'-strand, which is located behind the A-, B- and C-strands). The beta-hairpin is marked with an asterisk and the short helical region in the CD-loops with an alpha sign. b The RAdV-1 fibre head trimer. The three monomers are shown in green, magenta and cyan. The beta-hairpin and helical region are marked as in panel (a). c The RAdV-1 fibre head monomer (green; in the same orientation as in panel a) superposed onto the TAdV-3 fibre head monomer (dark blue). d The RAdV-1 fibre head trimer, coloured as in panel b, superposed onto the TAdV-3 fibre head trimer (dark blue). e Structure-based sequence alignment of the RAdV-1 and TAdV-3 fibre heads. Identical residues are indicated with lines, similar residues with dots. Beta-strands and the short helical region are highlighted. The residues that in the TAdV-3 fibre head structure interact with sialyllactose are underlined
