Symbols denote the presence (+) or absence (−) of a particular annotated transporter within each genome. Substrate specificity is inferred based upon KO annotated specificity of the substrate binding protein (ABC transporters) or the membrane linked EIIC components (PTS transporters).

¹Transport systems presented are limited to complexes showing co-localization of all genes needed to form a functional complex. Complexes lacking annotation of a single component are not included. Redundancy in transport systems exists, but is not identified.
