Summary

Thirty completely sequenced genomes of bacteria, archaea and eukaryotes have been surveyed for the presence of genes encoding homologues of known solute transport proteins. These analyses and others have revealed the presence of over 350 families of sequence-related transporters. All such proteins have been classified according to a system that we call the transporter classification (TC) system. In this short summary chapter, the main features of this system are described, and the families are presented.
