Annotation of overall regulated bacterial protein functions by enrichment of Gene Ontology (GO) terms.

<p>Based on the classifications of GO annotation, the overall bacterial functions were categorized into biological process, molecular function, and cellular component, and displayed in pie chart format. The numbers of GO terms for each of the three categories are shown, whereas the proportion of each specific subcategory is also provided. Subcategories with GO terms less than 1% are classified as “other”.
