Stability of ubiquitylated nucleosomes. a) Scheme of the chaperone assisted, FRET based assay to measure nucleosome stability, following ref. 15. The boxes indicate equilibria measured in this work. b, c) Nucleosome stability measured by FRET for the indicated histone dimers. (data from 2 independent experiments are included in the plot, error bars: instrumental error, they are smaller than the symbols; solid lines: Model in shown in a), for parameters, see Table s1).
