摘要 鉴定一个编码周氏啮小蜂谷胱甘肽S-转移酶序列的全长基因CcGSTS1,系统发育分析发现,该基因与丽蝇蛹集金小蜂NvGSTS6基因具有高同源性。体外表达、纯化的重组CcGSTS1可催化CDNB与GSH结合,最适反应pH为7.0。该试验为进一步研究周氏啮小蜂CcGSTS1基因功能奠定基础。

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
