The Metabolites of the Herbicide L-Phosphinothricin (Glufosinate) (Identification, Stability, and Mobility in Transgenic, Herbicide-Resistant, and Untransformed Plants).
Droge-Laser W., Siemeling U., Puhler A., Broer I.
The metabolism of the herbicide L-phosphinothricin (L-Pt) was analyzed in tobacco (Nicotiana tabacum), alfalfa (Medicago sativa), and carrot (Daucus carota).

The metabolism of the herbicide L-phosphinothricin (L-Pt) was analyzed in tobacco (Nicotiana tabacum), alfalfa (Medicago sativa), and carrot (Daucus carota). In transgenic, Pt-resistant plants expressing the Pt-N-acetyltransferase gene (pat), L-Pt was acetylated, resulting in two forms of N-acetyl-Pt (ac-Pt). In transgenic plants expressing only low pat-encoded acetylating activity as well as in genetically unmodified plants, three metabolic compounds 4-methylphosphinico-2-oxo-butanoic acid, 3-methylphosphinico-propanoic acid (MPP), and 4-methylphosphinico-2-hydroxy-butanoic acid (MHB) were identified. Hence, the transgene-encoded acetylation of L-Pt competes with a plant-specific degradation. The compounds MPP, MHB, and ac-Pt were found to be the final, stable products of the plant's metabolic pathways. The mobility of these stable compounds in the plant was investigated: L-Pt as well as the derived metabolites were found to be preferentially transported to the upper regions of the plant. << Less

Characterization of phosphinothricin acetyltransferase and C-terminal enzymatically active fusion proteins.

Enhanced expression of the bialaphos resistance (bar) from Streptomyces hygroscopicus, which confers resistance to the herbicides bialaphos and phosphinothricin (PPT), has been obtained in Escherichia coli using a vector system based on translational coupling. The gene product, PPT acetyltransferase, was purified to homogeneity and its enzymatic properties were analyzed. Hybrid gene constructs with gene fragments fused to the 3'-terminus of bar yield fusion proteins having acetyltransferase activity, with a Michaelis constant for the PPT substrate comparable to the unmodified enzyme. The bar gene represents a selectable and assayable reporter gene especially suitable for 3'-terminal gene fusions. << Less
