Table I. Result summary for the different N termini characterized for both the Arabidopsis and the human sample.
The NME percentage is the ratio of the modified proteins over the number of identified proteins, whereas the percentage of the different N termini is the ratio over the sum of all of the N termini characterized. Because a few proteins were identified with more than a single downstream NAA peptide (especially for the Arabidopsis sample), percentage values exceed 100%.
