| Type: | Family | Name: | Amino acid/peptide transporter family, dipeptide/tripeptide permease B |
| Description: | The transport of peptides into cells is a well-documented biological phenomenon which is accomplished by specific, energy-dependent transporters found in a number of organisms as diverse as bacteria and humans. The amino acid/peptide transporter family of proteins is distinct from the ABC-type peptide transporters and was uncovered by sequence analysis of a number of recently discovered peptide transport proteins []. This family consists of bacterial proton-dependent oligopeptide transporters, although they are found in yeast, plants and animals. They function by proton symport in a 1:1 stoichiometry, which is variable in different species. All of them are predicted to contain 12 transmembrane domains, for which limited experimental evidence exists. This entry represents a family of proton-dependent permeases that transport di- and tripeptides. | Short Name: | AA/pep_transptr_DtpB |
