An Intelligent System for Identifying Acetylated Lysine on Histones and Nonhistone Proteins

Figure 3

Two Sample Logo presents the compositional biases of amino acids around acetylation sites compared to the nonacetylation sites on histone and nonhistone sets. The significant amino acids around acetylated lysine residue are enriched from the positive dataset and presented in upper panel ( ). Relatively, the high frequency of amino acids around nonacetylated lysine is depleted from the negative dataset and presented in lower panel.
