The authors wish to correct errors in reported mass values in peptide identification to +711.3010 Da for the tryptophan cycloadduct and –695.3061 Da for the neutral loss fragment from the original values of +712.3088 Da and –696.3139 Da in the “Peptide identification in proteomics experiments” section of the Methods. The values are now updated in the HTML and PDF versions of the article.
