| Name | TRAP-T (tripartite ATP-independent periplasmic transporters) family transporters | |
| Type | SYSTEM | |
| Description | This property represents the presence of three-subunit transporters related to the DctPQM system for dicarboxylate transport in Rhodobacter capsulatus. These are secondary transporters, energized by ion gradients, rather than primary transporters powered by ATP directly. The acronym TRAP, or TRAP-T, stands for Tripartite ATP-independent Periplasmic Transporters. The characteristic architecture includes an integral membrane protein with 12 predicted transmembrane (TM) regions (e.g.DctM) and another with 4 predicted TM regions (e.g. DctQ). These two are fused in some species. Also present is an extracytoplasmic solute receptor (ESR), for which at least three families are known: DegP (TIGR00787), SmoM (PF03480), and TAXI (TIGR02122). In addition to C4 dicarboxylates, substrates moved by related transporters appear to include mannitol, aspartate derivative ectoine, and other as yet uncharacterized solutes. Some bacteria, such as Bradyrhizobium japonicum, may contain over a dozen such transporters. | |
