Figure 7.

C-terminal portion of gp33 and Ccm proteins are predicted to adopt the characteristic HK97-fold of phage coat proteins. Cartoon representation of the C-terminal portion of (a) ϕ12 gp33 (residues 127–402) and (b) SaPIbov5 Ccm (residues 83–355), generated by RaptorX [31]. Both proteins show similar folding to the prototypical coat protein from phage HK97 (c; PDB 1OHG). (d) Structural alignment of ϕ12 gp33 (a) and SaPIbov5 Ccm (b) models carried out with Mustang [33]. Identical residues are highlighted on a red background and conserved residues are in a blue box with red text. The elements of secondary structure for each model are shown above (gp33) or below (Ccm) the corresponding sequence.
