Acetylation sites in histone H3 from Physarum polycephalum
1983
Histone H3 from Physarum polycephalum was labelled with [3H]acetate in G2 phase of the cell cycle. Only histones H3 and H4 were labelled and the H4 was removed by chromatography. Sequential Edman degradation of labelled H3 showed that acetate was incorporated into residues 9, 14, 18 and 23 which correspond to the sites of acetyl-lysine determined in histones H3 from other organisms. The results confirm the sequence conservation of H3 and support the notion that data on H3 acetylation, obtained with Physarum, can be extrapolated to higher eukaryotes.
