Cloning and biochemical characterization of CG16936, a putative glutathione transferase in Drosophila Melanogaster / Tanusya Murali
CG16936, which was classified as DmGSTE12 was studied in this project. This study cloned and expressed CG16936 and the resulting recombinant CG16936 has been reactive towards 1,2-dichloro-4-nitrobenze (DCNB) (0.4324 μmol/min/mg) but of no activities towards, 1-chloro-2,4-nitrobenzene, trans-2-hexena...
