Fig. 6: The turnover rates of histones are accurately computed by the approach using two mass isotopomers.

Slow turnover rates of Histones are reflected in the time series of label incorporation obtained using complete (experimental) isotope profiles and reconstructed isotope profiles (using a pair of mass isotopomers). Shown are the labeling time series data of a peptide of histones: (a) H2A1B (histone 2A type 1-B), (b) H2B1B (histone 2B type 1-B), (c) H3.2 (histone H3.2), (d) H4 (histone H4), (e) H1.4 (histone H1.4), and (f) H2AY (core histone macro-H2A.1).
