Mechanistic Insights Into Post-translational α-Keto-β-Amino Acid Formation by a Radical S-Adenosyl Methionine Peptide Splicease

Adaptation to biotic and abiotic stress is crucial for the health of living organisms. In an article published in Nature Plants, Keppler et al. describe how the commensal microbiota triggers plant immune responses that feed back to tune microbial colonization of plants.

Metagenomic study of lake microbial mats reveals protease-inhibiting antiviral peptides from a core microbiome member

A recent “Chem” paper by the Piel group (IMB) in collaboration with the Chekan (UNC Greensboro) and Gugger groups (Institut Pasteur) reports a new and unusually complex steroid-like post-translational modification.

An organism as a tenant in another - in biology, this often works quite well. ETH researchers have now shed light on how such a partnership of a cell in a cell can establish.
