Heterologous expression experiments of three linaridin biosynthetic gene clusters revealed that the presence of multiple D-amino acids is a common feature of linaridin natural products, and unveiled the involvement of novel peptide epimerases conserved among linaridin clusters. By gene-deletion experiments, we also show that peptide epimerization occurs in the early stage of biosynthesis.
三个linaridin生物合成基因簇的异源表达实验表明,存在多个D-氨基酸是linaridin天然产物的共同特征,并揭示了linaridin簇中保守的新型肽差向异构酶的参与。通过基因缺失实验,我们还表明肽差向异构发生在生物合成的早期阶段。
