The distribution of known and putative polytopic cytoplasmic membrane transport proteins was determined bioinformatically for all organisms for which completely sequenced genomes were available. Transport systems for each organism were classified according to
(1) putative membrane topology,
(2) protein family,
(3) bioenergetics, and
(4) substrate specificities.
The overall transport capabilities of each organism were thereby estimated. The number of transporters identified in each organism varied drammatically, but was approximately proportional to genome size. Complete lists of the transporters from each organism are provided from the pull down menus on this page.
