Branches and twigs: the versatility of the branching module of the rhizoxin polyketide synthase was tested in an in vitro enzyme assay with (di)methylmalonyl-CoA extender units. Its ability to stereoselectively introduce two branches in one step by vinylogous addition expands the scope of previously studied PKS systems.
分支和树枝:在离体酶活性实验中,利用(di)甲基丙二酰
辅酶A延伸单元测试了根毒素聚酮合酶分支模块的多功能性。通过亲烯加成在一步中立体选择性地引入两个分支的能力扩展了先前研究的PKS系统的范围。
