Fig. 3. Comparison of functional categories of annotated transporters expressed at the protein level detected from two algal-bacteria co-cultures.

Categories based on Transport DB substrate identification and classed based on ChEBI (Chemical Entities of Biological Interest) ontology. “Other” category includes proteins that had only one protein identified from that category, and include categories of: polyamine, ion, choline, detergent, osmolyte, and antioxidant. Substrate identifications and TCDB classification can be found in Supplemental Data 3.
