A novel strategy based on carboxy group derivatization is presented for specific characterization of phosphopeptides. By tagging the carboxy group with 1-(2-pyrimidyl) piperazine (PP), the ion charge states of phosphopeptides can be largely enhanced, showing great advantages for sequencing phosphorylated
