Simulated MALDI-TOF data of equine myoglobin, labeled (with dimethylation) and control
Description
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.
Usage
myoglobin
Format
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".
