cDNA encoding an unclassified glutathione S-transferase (GST) of the diamondback moth, Plutella xylostella, was cloned by reverse transcriptase-polymerase chain reaction. The resulting clone was sequenced and the amino acid sequence deduced, revealing 67%-73% identities with unclassified GSTs from other organisms. A recombinant protein was functionally overexpressed in Escherichia coli cells in a soluble form and purified to homogeneity. The enzyme was capable to catalyze the transformation of 1-chloro-2,4-dinitrobenzene and ethacrynic acid with glutathione. A competition assay revealed that GST activity was inhibited by insecticides, suggesting that the enzyme could contribute to insecticide metabolism in the diamondback moth.
