摘要

Pristinamycin production in Streptomyces pristinaespiralis Pr11 is tightly regulated by an interplay between different repressors and activators. A gamma-butyrolactone receptor gene (spbR), two TetR repressor genes (papR3 and papR5), three SARP (Streptomyces antibiotic regulatory protein) genes (papR1, papR2, and papR4), and a response regulator gene (papR6) are carried on the large 210-kb pristinamycin biosynthetic gene region of Streptomyces pristinaespiralis Pr11. A detailed investigation of all pristinamycin regulators revealed insight into a complex signaling cascade, which is responsible for the fine-tuned regulation of pristinamycin production in S. pristinaespiralis.
