Improved Solid-Phase Peptide Synthesis of Wild-Type and Phosphorylated Phospholamban Using a Pseudoproline Dipeptide

摘要

In this study, we report that the insertion of a pseudoproline dipeptide for the solid-phase peptide synthesis of wild-type Phospholamban protein (WT-PLB) has two important advantages. First, it disrupts the formation of different secondary structures, which is responsible for poor couplings during the preparation of highly aggregated sequences. Second, it enhances the purities and solubility of crude products leading to easier HPLC purification.
