Heterologous expression of novobiocin and clorobiocin biosynthetic gene clusters.

ABSTRACT: A method was developed for the heterologous expression of biosynthetic gene clusters in different Streptomyces strains and for the modification of these clusters by single or multiple gene replacements or gene deletions with unprecedented speed and versatility. Lambda-Red-mediated homologous recombination was used for genetic modification of the gene clusters, and the attachment site and integrase of phage phiC31 were employed for the integration of these clusters into the heterologous hosts. This method was used to express the gene clusters of the aminocoumarin antibiotics novobiocin and clorobiocin in the well-studied strains Streptomyces coelicolor and Streptomyces lividans, which, in contrast to the natural producers, can be easily genetically manipulated.
