Proteomic quantification of lysine succinylation in human GC. a GO enrichment of quantified differentially expressed proteins. b Summary of differentially quantified sites and proteins (> 1.3 or < 0.77). c Motif analysis of all the identified succinylation sites. d KEGG pathway enrichment analysis of four groups of samples, Q1 (< 0.667), Q2 (0.667 ~ 0.769), Q3 (1.3 ~ 1.5), and Q5 (> 1.5) (Tumor-vs-Normal). e The protein-protein interaction (PPI) network analysis of differentially quantified sites and proteins (> 1.3 or < 0.77)
