Extended Data Fig. 5: Normalized frequencies of peptide cleavage patterns of selected proteins.
From: A late Middle Pleistocene Denisovan mandible from the Tibetan Plateau

Spectral counts are based on the total number of ammonium bicarbonate and acid-demineralization PSMs (six runs) and include both N and C termini of each aligned PSM. Red colours indicate more PSMs than expected and green colours fewer PSMs than expected, compared to a random cleavage model for each protein separately. Note differences in colour scale. The title of each plot refers to the UniProt accession code for the relevant protein.
