Protein metabolism cluster of the functional enrichment network for biological processes based on the related functions of the differentially expressed genes (DEGs) in the anterior-mid intestine of gilthead seabream (Sparus aurata) fed experimental low fishmeal diets containing Debaryomyces hansenii (1.1%, 17.2 × 105 CFU; Yeast diet) or devoid of the probiotic (Control diet). The node size determinate the significance (Bonferroni step-down correction; small P < 0.05; medium P < 0.005; large P < 0.0005), the node colour determinate the principal GO process aggrupation, and the node numbers indicate different GO process classified in Additional file 1: Table S4
