Directed Oxidative Folding of Disulfide-Rich Peptides (DRPs) Using a Pseudoproline Unit: Ion Mobility-Mass Spectrometry (IM-MS) Reveals the Conformational Landscape of the DRP
Disulfide-rich peptides (DRPs) are attractive drug development scaffolds due to their exceptional stability and specificity. Regioselective disulfide bond formation is often achieved via orthogonal Cys protecting groups or strategic Pro placement. However, Cys protection strategies are labor-intensive and low-yielding,...
