... December 2008) doi:10.1111/j.1742-4658.2009.06866.x l-Canavanine occurs as a toxic non -protein amino acid in more than 1500 leguminous plants. One mechanism of its toxicity is its incorporation into proteins, replacing l-arginine and giving rise ... the guanidinium g-N but also comes into contact with the adenosine ring of Ade76. There is a general consensus that tRNA b...
