The top citrullination proteins from [36] were up-loaded into Bingo and analyzed for enriched molecular function ontologies. Orange nodes represent the most significantly enriched gene ontology terms, whereas white and yellow represent the least significantly enriched gene ontology terms. The Bingo analysis highlights the hierarchic of the ontologies. For this dataset the most enriched Molecular Function terms were: hydro-lyase activity, carbon-oxygen lyase activity, oxidoreductase activity, NAD or NADH binding, lyase activity, troponin C binding, and enoyl-CoA hydratase activity.
