How do Actinomyces Coordinate Secondary Metabolite Production in Response to their Environment?

Actinomyces bacteria are invaluable due to their highly diverse secondary metabolites. Many of which are used in medicine, e.g. as antibiotics. From genome sequencing it became evident that Actinomyces possess many more gene clusters for secondary metabolite production than products have been identified from them. Under usual laboratory conditions Actinomyces obviously have no need to produce all these compounds whereas under particular conditions it can be expected that most of these compounds are produced in response to certain environmental challenges. 

This project aims to reveal how Actinomyces react to environmental factors, e.g. heavy metal ion stress or cocultivation with other organisms. Using differential metabolite profiling the differences in secondary metabolim between varying growth conditions will be revealed. Induced secondary metabolites will be identified using a combination of mass spetrometry, NMR and genome mining. The biological function of identified metabolites will be studied in appropriate bioassays. In addition, the pharmaceutical value of newly identified compounds will be investigated. Moreover, the molecular basis of factors leading to the induced production of secondary metabolites should be addressed.

We will follow an interdisciplinary approach combining techniques of microbiology, genome mining and analytical chemistry, Therefore, a stron interest and background in natural products chemistry, analytical chemistry (mass spectrometry and NMR) and/or genome mining is required.

The project is funded by a fellowship.
