Fig. 3: A global view on peptide cross sections.

From: Deep learning the collisional cross sections of the peptide universe from a million experimental values

Fig. 3

a Mass-to-charge vs. collisional cross section distribution of all peptides in this study colored by the GRAVY hydrophobicity index (n = 559,979). b Subset of peptides with C-terminal arginine or lysine colored by the fraction of prolines in the linear sequence (n = 452,592). c Histidine-containing peptides of (b) colored by the relative position of histidine (n = 171,429). Trend lines (dashed) are fitted to the overall peptide distribution to visualize the correlation of ion mass and mobility in each charge state.
