PTR2

PTR2
PFAM accession number:PF00854
Interpro abstract (IPR000109):

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 [(PUBMED:7476181)]. They seem to be mainly involved in the intake of small peptides [(PUBMED:7817396)]. However, some family members are nitrate permeases and others are involved in histidine transport [(PUBMED:17481610)].

GO process:transmembrane transport (GO:0055085)
GO component:membrane (GO:0016020)
GO function:transmembrane transporter activity (GO:0022857)
