A new signal–receptor pair involved in regulating biofilm formation and virulence was detected in Vibrio cholerae. Both the signal and the transcription factor belong to common classes of natural products and receptor proteins, suggesting widespread importance of related systems in nature.

Targeted protein degradation: You can glue it too!

April 13th, 2017 by Michal J Walczak

Proteolysis-targeting chimera (PROTACs) are synthetic molecules that recruit neo-substrate proteins to a ubiquitin ligase for ubiquitination and subsequent degradation. Structural insight into the VHL–MZ1–BRD4 complex reveals how the rationally designed MZ1–PROTAC molecule mediates degradation of an unnatural protein substrate.

CRISPR–Cas9 strategy for activation of silent Streptomyces biosynthetic gene clusters

April 10th, 2017 by Mingzi M Zhang

Nature Chemical Biology 13, 607 (2017). doi:10.1038/nchembio.2341

Here we report an efficient CRISPR–Cas9 knock-in strategy to activate silent biosynthetic gene clusters (BGCs) in streptomycetes. We applied this one-step strategy to activate multiple BGCs of different classes in five Streptomyces species and triggered the production of unique metabolites, including a novel pentangular type II polyketide in Streptomyces viridochromogenes. This potentially scalable strategy complements existing activation approaches and facilitates discovery efforts to uncover new compounds with interesting bioactivities.
