Precursor-directed polyketide biosynthesis was demonstrated in the heterologous host Escherichia coli. Several diketide and triketide substrates were fed to a recombinant E. coli strain containing a variant form of deoxyerythronolide B synthase (DEBS) from which the first elongation module was deleted resulting in successful macrolactone formation from the diketide, but not the triketide, substrates.
在异源宿主大肠杆菌中证实了前体导向的聚酮生物合成。将几种二酮和三酮底物加入到含有来自脱氧红霉内酯B合酶(DEBS)变体形式的重组大肠杆菌菌株中,该变体形式的第一个延伸模块被删除,结果二酮底物成功形成了大环内酯,但三酮底物未成功。
