I don't think so. I have previously encountered this sort of numbering
with a protein
that was numbered with reference to another protein, and the 100A etc
appeared where
the protein had insertions as compared to the reference sequence. You
will probably
need to hunt down the paper introducing this sequence if you want to
know exactly which
protein is considered to be the reference.
best wishes,
