The production of antibiotics in different Streptomyces strains has been reported to be stimulated by the external addition of S-adenosylmethionine (SAM) and by overexpression of the SAM synthetase gene metK. We investigated the influence of SAM addition, and of the expression of SAM biosynthetic genes, on the production of the aminocoumarin antibiotic novobiocin in the heterologous producer strain Streptomyces coelicolor M512 (nov-BG1). External addition of SAM did not influence novobiocin… CONTINUE READING
