Structure:

Glufosinate is a non-selective post emergence herbicide that controls weeds by irreversibly inhibiting the enzyme glutamine synthetase. Glutamine synthetase incorporates glutamate and ammonia to form the amino acid glutamine. The enzyme has different isoforms contained in leaves and roots. The root isoform of glutamine synthetase was shown to have greater sensitivity to phosphinothricin (glufosinate) than the chloroplast isoform in both Sinapis alba and Triticum aestivum. Inhibition of this enzyme causes a large buildup of ammonia in plant cells as well as depleting the plant of crucial amino acids, and inhibiting photosynthesis. The accumulation of ammonia in plant cells due to glutamine synthetase inhibition was initially thought to cause the observed phytotoxcicity.
