Comparison of Vmp-1 and Vmp-2. A and C: the predicted coiled-coil regions of Vmp-1 and Vmp-2, respectively. A threshold value of 0.5 is shown as a vertical dashed line. B: The identity (similarity) displayed by regions of the Vmp proteins. The C-terminal regions of the protein showed high mutual similarity. Green bars are shown below the repeated sequence of Vmp-2. A red bar indicates the fragment specific for Vmp-1 used for generation of a polyclonal antibody.
