[i] The transport mechanisms have been classified as diffusion (exchange of only a primary metabolite), symport (a primary and secondary metabolite transported in the same direction), antiport (a primary and secondary metabolite transported in opposite directions), or other (ABC transporters and ADP/ATP exchange reactions). For each membrane/mechanism combination, the number of gene-associated reactions is shown in parentheses next to the total number of reactions in that category.
