a AANterm: Identified N-terminal arginylated or additionally modified (Gln30) amino acid, the superscript number indicates the position number of the amino acid from the corresponding protein model.
b a1 ion: a1 ion of an N-terminally dimethylated arginine is traceable in assigned spectra.
c Nr of spectra: total number of spectra for the arginylated N-terminus across all experiments.
d Length of the corresponding protein model (number of amino acids).
