The deduced amino acid sequence of the epsp synthase from psedomonas fluorescens g2 was compared to epsp synthase from various species . it shares 30 % homology with the epsp synthases from e . coli and salmonella typhimurium in class i and is different from patent - protected mutational sites 将本实验获得的荧光假单胞菌g2epsp合成酶推导的氨基酸序列与class中大肠杆菌和鼠伤寒沙门氏菌来源的epsp合成酶同源性约为30 ，且不含有专利保护的突变位点。
2.
It shares less than 25 % homology with the epsp synthases in class ii . it also shares 24 . 5 % homology with the epsp synthase isolated by monsanto company and does not contain any conservative sequences and mutational sites protected by patents . all of the above shows great potential for future development 与class的epsp合成酶同源性低于25 ，其中与monsanto公司分离的根癌农杆菌( agrobacteriumtumefaciens ) cp4来源的epsp合成酶同源性仅为24 . 5 ，且不含有专利保护的保守序列和突变位点，显示了良好的开发应用潜力。
