ClbR Is the Key Transcriptional Activator of Colibactin Gene Expression in Escherichia coli

open access: yesmSphere, 2020
Colibactin is a nonribosomal peptide/polyketide hybrid natural product expressed by different members of the Enterobacteriaceae which can be correlated with induction of DNA double-strand breaks and interference with cell cycle progression in eukaryotes.

Targeted induction of a silent fungal gene cluster encoding the bacteria-specific germination inhibitor fumigermin

open access: yeseLife, 2020
Microorganisms produce numerous secondary metabolites (SMs) with various biological activities. Many of their encoding gene clusters are silent under standard laboratory conditions because for their activation they need the ecological context, such as ...
