Homologous Superfamily

TRAP transporter solute receptor DctP superfamily (IPR038404)

Short name: TRAP_DctP_sf

Overlapping entries


Substrate-binding proteins (SBPs) are extracytoplasmic proteins involved in substrate recognition for several different bacterial transporters. This entry represents the DctP superfamily of the substrate-binding proteins. They are part of the DctP-TRAP (tripartite ATP-independent periplasmic) transporter. Proteins in this superfamily include DctP from R. capsulatus, SiaP from Haemophilus influenzae [PMID: 20584082], DctB from Bacillus subtilis [PMID: 10708364] and TeaA from Halomonas elongata [PMID: 18702523].

The tripartite ATP-independent periplasmic (TRAP) transporters are substrate-binding protein (SBP)-dependent secondary transporters found in prokaryotes. They consist of a substrate-binding protein (SBP) of the DctP or TAXI families and two integral membrane proteins that form the DctQ and DctM protein families [PMID: 20584082].
