Overview

The study demonstrates stiffening of MUC5AC peptides through glycosylation in peptides, suggesting structural implications.

Key Points

  • Glycosylation of MUC5AC peptides significantly increases stiffness, indicating a structural transformation.
  • Peptides with up to 30 GalNAc residues showcased improved synthesis methods, achieving 100% occupancy of glycosylation sites.
  • Automated synthesis involving diselenide–selenoester ligation enabled efficient glycoeconomic synthesis of complex peptides.
  • The findings reveal structural shifts in peptide conformation, suggesting deeper implications for mucin biology and function.
