Distribution and motif analysis of lysine acetylation sites. a Pie chart illustrating the number and percentage of lysine acetylation sites per protein. b Heat map of the amino acid compositions around the lysine acetylation sites showing the frequency of different types of amino acids surrounding this residue. c Sequence probability logos of significantly enriched acetylation site motifs for ±10 amino acids around the lysine acetylation sites. d Number of identified peptides contained in each conserved motif
