Fig. 4: Analysis of ADP-ribosylation fragmentation patterns.
From: Detecting diagnostic features in MS/MS spectra of post-translationally modified peptides
a ADP-ribosylation diagnostic ion presence in modified and unmodified spectra. Features detected in both datasets were averaged across all values. b Structure of ADP-ribosylation. Dashed lines correspond to breakpoints in the molecule. c ADP-ribosylation peptide remainder mass presence in modified and unmodified spectra. d Correlation between average intensity of diagnostic ions and their presence in unmodified spectra across both datasets. 95% confidence intervals for regression estimates are highlighted. Source data are provided as a Source Data file.
