  • * Lysine (4.6 pmol) and 11 pmol of alanine were found in the first sequencing cycle, probably because the tryptic peptide was partially cleaved at the Arg-Lys bond, giving rise to a mixture of two peptides, one starting with a lysine, one with an alanine. 

  • Xxx represents a position where no amino acid could be definitively assigned.
