Conserved acetylated sites on histone N-termini shared by ten oomycetes species. a Computational predictions of histone acetylation sites on H2A, H2B, H3 and H4. The numbers indicate the positions of amino acids on the histone tails. b Frequency distribution of amino acids surrounding lysines in acetylated and non-acetylated histones. Frequency of amino acids (y axis) spanning positions −6 to 6 (x axis) showed differences in predicted acetylated lysines (698) (left) and non-acetylated lysines (321) (right) in the core histone protein. For sequences of lysines that are located close to each other, only one of them was picked up by analysis. Residues in polar amino acids are indicated in green, and the basic, acidic and hydrophobic amino acids are indicated in blue, red and black, respectively
