"The protein Monsanto analysed was from E.coli, not from RoundUp
ready soybeans! Testing assumed the protein expressed in the
bio-engineered soybean has the same amino acid sequence as the soil
bacterium E coliform from which the genetically engineered gene was
extracted. This can only be verified when the soybean-produced
protein is isolated and the amino acid sequence is determined.
Exchanging genes between bacteria and a higher organism can
sometimes result in partial change of amino acid and/or
post-translational modification after expression. It was presumed
Monsanto had determined the amino acid sequence of the GE soybean
but it had not.
Monsanto sequenced only 15 amino acids from the protein that was
expressed in E. coliform. The rest of the sequence was an assumption
about the sequence of the bacterial DNA. They determined only 3.3%
of the expected total of 455 amino acids and the protein is not from
soybeans. The test described in the documents is the only method to
verify antigenic equivalence of proteins. But antigenic similarity
itself does not prove that the amino acid sequences are the same.
The real sequence of the GE protein in the soybean that we are
eating is still unknown".
Japan does not want GM rice or wheat as can be seen on http://www.mindfully.org/GE/GE4/Monsanto-Rice-Failed-Japan5dec02.htm because they have tested Monsanto's scientific evidence and found major flaws. 580,000 people signed the petition against it. I am not the only concerned consumer it seems.
