InterPro : IPR004748

Name  Polyol permease Short Name  Polyol_permease
Type  Family Description  Proteins in this entry are mostly known or predicted polyol transporters. The best characterised of these proteins are DalT and RbtT from Klebsiella pneumoniae, which tranpsort D-arabinatol and ribotol respectively. Like other members of the Major Facilitator Superfamily (MFS), DalT and RbtT appear to be secondary transporters capable only of transporting solutes in response to chemiosmotic ion gradients []. They contain a total of twelve predicted transmembrane helices; six in the N-terminal portion of the protein, and six in the C-terminal portion. Residues defining substrate specificity lie in the N-terminal region of these proteins.
