Novel group B streptogramin-like compounds of general formula (I), and a method for preparing streptogramines by mutasynthesis using a mutated micro-organism to influence the biosynthesis of at least one of the precursors of group B streptogramins are disclosed. Novel nucleotide sequences involved in the biosynthesis of said precursors, and their uses, are also disclosed.
                            本发明公开了通式(I)的新型B组链球菌素类化合物,以及通过使用突变的微
生物进行mutasynthesis制备链球菌素的方法,以影响B组链球菌素的至少一个前体的
生物合成。本发明还公开了参与前体
生物合成的新型核苷酸序列及其用途。
