Abstract: AbstractLasso peptides are a class of bioactive ribosomally synthesized and post-translationally modified peptides (RiPPs) characterized by a mechanically interlocked topology, where the C-terminal tail of the peptide is threaded and trapped within an N-terminal macrolactam… read more here.

DOI: 10.1073/pnas.2204161119
Abstract: Significance The conformational changes that accompany signaling events in transmembrane chemoreceptors are difficult to follow with structural methods that cannot replicate the native cellular environment. We developed in vivo cysteine crosslinking reporters of the Escherichia… read more here.

DOI: 10.1103/physrevlett.130.198201
Abstract: Glasses obtained from vapor deposition on a cold substrate have superior thermodynamic and kinetic stability with respect to ordinary glasses. Here we perform molecular dynamics simulations of vapor deposition of a model glassformer and investigate… read more here.
