Peptide-level reanalysis finds a small cleavage shift but no major accessibility bias under osmotic stress

Environmental stress can alter protein folding, molecular interactions, aggregation state, and protease accessibility before proteomic sample preparation. I reanalyzed the publicly available *Yersinia pseudotuberculosis* TMT11plex proteomics data associated with Süer et al. (PNAS, 2026) to test whether the 0.5 M NaCl o...
