[Biopython-dev] Kabat wire ( or wild goose ) chase

[Cayte]

  I found that the subscripts of the Kabat numbers do not represent
alternatives.  A helpful email informed me that  more than likely the
letters flag insertions compared to a reference.  When I checked the PubMed
reference for a Kabat output file, I found that the sequence in the NCBI
nucleotide database matched the Kabat residues chained together,without any
special handling of the subscripted residues.  My guess is that the
reference used is the canonical form, sort of a template for what a plain
vanilla antibody should contain.
