Abstract In this study,we characterized a full-length gene encoding GST sequences CcGSTS1 from C.cunea.Phylogenetic analysis showed that CcGSTS1 shared the highest identity with NvGSTS6 of Nasonia vitripennis.The recombinant CcGSTS1 showed glutathione-conjugating activity toward CDNB (1-chloro-2,4-dinitrobenzene) and GSH (Glutathione).The optimal reaction pH value is 7.0.This study provides a foundation for further study on the function of CcGSTS1 gene in C.cunea.
Key words Chouioia cunea Yang;Glutathione S-transferases;Phylogenetic analysis;Enzyme activity
