^aAccording to the Transporter Classification Database (http://tcdb.org)
^bNumber of RBH-Hits Identified by Reverse-Blast-Hit(RBH) at 60% Identity and 50% Coverage to TCDB
^cAn unusual over-representation of hits corresponding to the Bovine UniProt Annotations was observed for this category (i.e., 41 for Combined Fish and 28 for T. californica)
^dTransporter Classes having two or less hits were grouped into this category. They include: Ribosomally synthesized protein/peptide toxins/agonists that target channels and carriers, Transcompartment Lipid Carrier, Cell Fusion Pores, Choline/EthanolaminePhosphotransferase 1, Polysaccharide Synthase/Exporters and Holins
