Chemical ligation of epoxide-containing fusicoccins and peptide fragments guided by 14-3-3 protein

The template effect of 14-3-3 protein on the chemical ligation of fusicoccin derivatives containing an epoxide group and the pentapeptide QSYDC was investigated. HPLC analysis of the epoxide-opening reaction demonstrated that 14-3-3ζ protein improves the yield of the conjugate product compared to the protein-free control.
