[BiO BB] Structure/Sequence Alignment

  Try using ClustalW.  It lets you load in the structure template's
secondary structure as a numeric profile that weighs position-specific gap
penalties.  This typically forces gaps into unstructured regions of the
protein structure.  You can make a multiple sequence alignment of the
sequences and then generate a profile-profile alignment.
