Functional classification and enrichment analyses of differentially lysine-succinylated proteins in IPEC-J2 cells. A Enrichment analysis of KEGG pathways by differentially lysine-succinylated proteins. B COG annotation of differentially lysine-succinylated proteins. C Differentially lysine-succinylated proteins in the glycolysis pathway. The green box shows that the lysine succinylation levels of the corresponding proteins in K. slooffiae (KS) group were lower than those in the control (Ctrl) group. The yellow box shows that there were upregulated and downregulated lysine-succinylated sites in the corresponding proteins comparing the KS group with the Ctrl group. D–F Glucose consumption (D), lactate production (E), and ATP content (F) in IPEC-J2 cells. Data are presented as mean ± SEM (n = 6) and evaluated by Student’s t-test in D–F. **p < 0.01
