 Project objective

The aim of the StrepCrypPath is to test the industrial potential of a new approach to enhance Streptomyces secondary metabolism, discovered in our ERC-StG Strp-differentiation (280304) project. We discovered a pleiotropic regulator of differentiation and secondary metabolism in the S. coelicolor model strain. The S. coelicolor strain lacking this regulator is the first Streptomyces reported to produce secondary metabolites during its whole developmental cycle, including germination, the exponential growth phase and the stationary stage. S. coelicolor encodes 30 secondary metabolites, but only two are produced in high amounts under the culture conditions used in our lab. The expression of 15 secondary metabolite clusters (50% of the total), including 6 predicted to participate in secondary metabolite biosynthesis never observed in the lab (cryptic pathways), is activated/enhanced, in our mutant.

The gene encoding this new regulator is highly conserved in Streptomyces. We will explore if the inactivation of the orthologues of this regulatory gene in industrial streptomycetes causes the same phenotype observed in S. coelicolor: secondary metabolism and cryptic pathway activation. We will create integrative conjugative plasmids harbouring antisense mRNAs to inactivate this gene. We do not expect that this method will enhance and/or activate all secondary metabolite clusters. However, if as it happens in S. coelicolor, we can activate/enhance 50% of the secondary metabolite pathways, including several cryptic pathways, in any streptomycete, we can revolutionise the screening for new secondary metabolites from streptomycetes.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
