| + | Glutathione S-transferases (GSTs) from the phi (GSTF) and tau (GSTU) classes are unique to plants and play important roles in stress tolerance and secondary metabolism as well as catalyzing the detoxification of herbicides in crops and weeds. We have cloned and functionally characterized a group of GSTUs from wheat treated with fenchlorazole-ethyl, a herbicide safener. One of these enzymes, TaGSTU4-4, was highly active in conjugating the chemically distinct wheat herbicides fenoxaprop and dimethenamid. The structure of TaGSTU4-4 has been determined at 2.2 A resolution in complex with S-hexylglutathione. This enzyme is the first tau class GST structure to be determined and most closely resembles the omega class GSTs, but without the unique N-terminal extension or active site cysteine. The X-ray structure identifies key amino acid residues in the hydrophobic binding site and provides insights into the substrate specificity of these enzymes. | ||
