Fig 2. KEGG pathway enrichment and protein interaction analysis of S-nitrosylation in A549 cells.

Fig 2

(A) Overrepresented KEGG pathways among the identified candidate SNO proteins, ranked by the normalized enrichment fold (see Materials and Methods for details). Proteins were classified into different categories based on KEGG annotations and using the Genecodis algorithm (see also Sheet I in S1 Table). (B) SNO proteins identified in the cytokine data set tend to be functionally related based on protein interaction networks. The diagram shows all high-confidence protein-protein interactions from the STRING interaction database [34].
