Protein Family Models

This family includes Swiss:P33413 which is not in the Prosite entry. Membership of this family is supported by a significant blast score. (from Pfam)

This family consists of the sodium/proline symporter (proline permease) from a number of Gram-negative and Gram-positive bacteria and from the archaeal genus Methanosarcina. Using the related pantothenate permease as an outgroup, candidate sequences from Bifidobacterium longum and several from archaea are found to be outside the clade defined by known proline permeases. These sequences, scoring between 570 and -40, define the range between trusted and noise cutoff scores.

Members of the SSS family have been identified in bacteria, archaea and animals, and all functionally well characterized members catalyze solute uptake via Na+ symport. Proteins of the SSS generally share a core of 13 TMSs, but different members of the family may have different numbers of TMSs. A 13 TMS topology with a periplasmic N-terminus and a cytoplasmic C-terminus has been experimentally determined for the proline:Na+ symporter, PutP, of E. coli.
