This example data is loosely based on the predicted MALDI-TOF mass list of tryptic peptides of equine myoglobin, created using entry P68082 (MYG_HORSE) in UniProtKB (https://www.uniprot.org/uniprot/P68082) with further modification. Labeled peptides, either singly or doubly dimethylated, present 28 or 56 Da shfit relative to the control.

myoglobin

a tibble dataset of 193 rows and 7 variables.

mass: the mass of singly protonated peptides, in Dalton. Cysteins were alkylated with iodoacetate.
position: the positions of the N- and C-termini of peptides, counting from signal amino acid methionine. The position number of N-terminus of mature protein starts at number 2.
no.MC: number of mis-cleavages, which are cites of C-termini of lysines and arginines (without following proline) where trypsin fail to digest apart.
peptide.sequence: the sequence of the tryptic peptides of myoglobin, composed of amino acids' single-letter abbreviations.
group: four experimental groups, consisting "label1", "label2", "label3", and "control"
err: error of the mass, in Dalton.
err.ppm: error of the mass, in parts per million (ppm) .
intensity: peak intensity, in "counts".
