The macrocyclic polyketide tacrolimus (FK506) is a potent immunosuppressant that prevents T-cell proliferation produced solely by Streptomyces species. We report here the first draft genome sequence of a true FK506 producer, Streptomyces tsukubaensis NRRL 18488, the first tacrolimus-producing strain that was isolated and that contains the full tacrolimus biosynthesis gene cluster.
大环多酮类免疫抑制剂他克莫司(FK506)是一种强效免疫抑制剂,可阻止 T 细胞增殖,而这种物质仅由链霉菌属产生。我们在此报告了第一个真正的 FK506 产生菌——链霉菌筑波变种 NRRL 18488 的基因组草图序列,这是第一个被分离出来的、含有完整他克莫司生物合成基因簇的产他克莫司菌株。
