... peptides usually exhibit abundant C-terminal sequence ion series. However, when a tryptic peptide with C-terminal Lys contains a His-residue close to its N-terminus, the ion series observed may be controlled by this site and in such a case the spectrum will be dominated by N-terminal sequence ions. ...
