Molecular insights on the biosynthesis of antitumour compounds by actinomycetes.

Olano C, Méndez C, Salas JA - Microb Biotechnol (2010)

Bottom Line: The characterization of these clusters has represented, during the last 25 years, a great source of genes for the generation of novel derivatives by using combinatorial biosynthesis approaches: gene inactivation, gene expression, heterologous expression of the clusters or mutasynthesis.In addition, these techniques have been also applied to improve the production yields of natural and novel antitumour compounds.In this review we focus on some representative antitumour compounds produced by actinomycetes covering the genetic approaches used to isolate and validate their biosynthesis gene clusters, which finally led to generating novel derivatives and to improving the production yields.
