Bioinformatic analysis of lysine succinylation sites in D. officinale. a Plot shows relative abundance of amino acids flanking succinylated lysine. The relative abundance was counted and schematically represented by an intensity map. The intensity map shows enrichment of amino acids in specific positions of succinylated lysine (10 amino acids upstream and downstream of the succinylation site). b Probability sequence motifs of succinylation sites consisting of 10 residues surrounding the targeted lysine residue using Motif-X. Two significantly enriched succinylation site motifs were identified. c Analysis of functional preference for different motifs in D. officinale. The results were showed by a Venn Diagram
