Abstract

The Putative Sulfate Exporter (PSE) family consists primarily of bacterial and some archael family members. It is not yet functionally characterized and is tentatively placed into this family based on its folds. PSE family members are predicted to have 11 transmembrane segments (TMSs). The phylogeny, topology, internal homology, and functionality of the PSE family were analyzed. Evidence suggests that the PSE encoding genes are located on mobile genetic elements, and a 6 + 1 + 6 or 7 x 2 TMS repeat is proposed based on the alignments from SSSearch and GAP. SEED analysis shows that it is likely a sulfate exporter
