Structure of the BAdV-4 fibre head domain. a. Monomer structure coloured by secondary structure. Beta-strands and most of the loops are labelled. b. Top view of the trimer with the three monomers coloured differently. An asterisk indicates the GHID-sheet in the yellow monomer and most loops are labelled. c. Topology diagram of the BAdV-4 fibre head, with start and end residues of each beta-strand and of the alpha-helix labelled. d. Topology diagram of the HAdV-5 fibre head, shown for comparison. e. Superposition of the HAdV-5 fibre head monomer onto the BAdV-4 fibre head monomer in the same orientation as part A. f: Superposition of the HAdV-5 fibre head trimer onto the BAdV-4 fibre head trimer (top view). Surface loops of the HAdV-5 fibre head trimer are indicated
