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。
