Insight into β-Hairpin Stability: Interstrand Hydrogen Bonding
摘要:
For evaluation of the role of interstrand hydrogen bonding for -hairpin stability, two cyclic peptides differing only in side chain hydroxy-to-methyl substitution were designed and synthesized on solid phase following the Fmoc-t-Bu-Trt protection strategy. Subsequent to cyclization in solution, combined computational and experimental ensemble analysis revealed higher conformational stability of the peptide capable of interstrand hydrogen bonding.
