Bt is not a lectin!!



Lest anyone miss the mesage of the last email:

The key Bt proteins are NOT lectins by any reasonable definition!

See "Lectins", 1989, by Sharon and Lis and published by Chapman and Hall.
They describe a wide range of other sugar binding molecules that are also
not considered to be lectins.  Even antibodies have properties similar to
lectins in that they agglutinate, which Bt crystal proteins (the genes for
which are placed into plants) do not do.

It is not even clear that Bt crystal proteins even bind to sugars directly,
but instead it appears that they bind to other molecules that hold the
sugars.
