TESTBIOTECH Background 17 - 7 - 2021
Oilseed rape 73496 is genetically engineered to be herbicide-resistant to glyphosate. The oilseed rape expresses the glyphosate acetyltransferase protein GAT4621. Glyphosate inhibits the enzyme enolpyruvulshikimate-3-phosphate synthase (EPSPS), which is involved in the biosynthesis of aromatic amino acids. GAT proteins acetylate glyphosate giving rise to N-acetyl glyphosate, which has no herbicidal activity.
Implementing Regulation 503/2013 was not applied in this case.
