Fig 4. Gene Ontology (GO) analysis of proteins with a significant interaction (s x m x h, s x h | m) or main effect of strain indicates that the majority of differential proteins are involved in catalytic activity.

GO analysis was performed by inputting gene symbol abbreviations (e.g. ADH, PflB, Dha1) into the gene list analysis tab within the PANTHER classification webpage (http://www.pantherdb.org/) and searching against the S. aureus database within the PANTHER Classification System Database [53].
