PROCESS FOR PREPARATION OF TACROLIMUS

摘要

Genetically modified strains of Streptomyces tsukubaensis (S. tsukubaensis) can be used for an improved fermentation process for the preparation of tacrolimus or a salt or derivative thereof by cultivation of these genetically modified strains. Novel genes allowing biosynthesis of allylmalonyl-CoA can be used for polyketide production with allylmalonyl extender unit.
