Effects of histone acetylation on the structure of nucleosomes. 601A and 601B nucleosomes labeled with Cy3 and Cy5 displayed FRET efficiencies of 0.69 and 0.55, respectively (black in histogram) [13]. Signal integration time is 35 ms. Upon acetylation (red in histogram), the FRET efficiency of 601A nucleosome was decreased whereas the FRET efficiency of 601B nucleosomes was increased [13].
