Nonomuraea sp. ATCC 39727 belongs to the Streptosporangiaceae family of filamentous actinomycetes. This microorganism produces the teicoplanin-like glycopeptide A40926, which is the starting material for the synthesis of the second-generation glycopeptide dalbavancin. Notwithstanding the strain's pharmaceutical relevance, the lack or poor efficiency of genetic tools to manipulate Nonomuraea sp. ATCC 39727 has hampered strain and product improvement. Here we report the development of gene transfer systems based on protoplast transformation and intergeneric conjugation from Escherichia coli. Efficiency of transformation and conjugation, followed by site specific or homologous recombination with the Nonomuraea sp. genome, were determined using the integrative plasmid pSET152 (5.7 kb), and the Supercos1 derivative cosmid A40ΔY (30 kb). To our knowledge, this is the first report of the transformation of protoplasts of Nonomuraea sp. ATCC 39727, even though the improved procedure for intergeneric conjugation makes it the method of choice for introducing large segments of DNA into Nonomuraea sp. ATCC 39727.
