Compositions and methods are provided to detoxify an auxin-analog herbicide through the use of at least one GH3 polypeptide having amino acid/auxin analog herbicide conjugation activity. Such GH3 polypeptides in the presence of an auxin-analog herbicide will produce an amino acid/auxin-analog conjugate having reduced herbicidal activity. Various methods of employing the GH3 polypeptides and the polynucleotides encoding the same are provided. Such methods include methods to detoxify an auxin-analog herbicide comprising applying to a plant, a plant cell or a seed an auxin-analog herbicide, wherein the plant, plant cell or seed comprises a heterologous polynucleotide encoding a GH3 polypeptide, and expression of the GH3 polypeptide produces a non-herbicidal aspartate/auxin-analog conjugate or a glutamate/auxin-analog conjugate. Additional methods for controlling at least one weed in an area of cultivation comprising a crop or a seed of the crop are provided, as are methods of detoxifying a contaminated material having an auxin-analog herbicide.
