Short name: POT_fam

Family relationships

Description

The proton-dependent oligopeptide transporter (POT) family (also known as the peptide transport (PTR) family) is made up of a group of energy-dependent transporters found in a organisms as diverse as bacteria and humans. The POT family of proteins is distinct from the ABC-type peptide transporters and was uncovered by sequence analyses of peptide transport proteins [PMID: 7476181]. They seem to be mainly involved in the intake of small peptides [PMID: 7817396]. However, some family members are nitrate permeases and others are involved in histidine transport [PMID: 17481610].
