    • Whereas the sequences of the tryptic-type peptides were selected to vary the position of the His residue, a protein database search () found 1040 proteins that would produce these peptides upon trypsinolysis.

    • Several tryptic pentapeptides containing phosphoserine (pSAAAX, ApSAAX, AApSAX, and AAApSX, where X = R or K) showed ECD and ETD spectra that were quite analogous to those reported here for the histidine-containing pentapeptides. These results are beyond the scope of the present work and will be reported separately.
