Protein Family Models

This family contains a diverse range of predicted transporter proteins. Including the DctM subunit of the bacterial and archaeal TRAP C4-dicarboxylate transport (Dct) system permease. In general, C4-dicarboxylate transport systems allow C4-dicarboxylates like succinate, fumarate, and malate to be taken up. TRAP C4-dicarboxylate carriers are secondary carriers that use an electrochemical H+ gradient as the driving force for transport. DctM is an integral membrane protein that is one of the constituents of TRAP carriers [1]. Note that many family members are hypothetical proteins. [1]. 11803016.

Tripartite ATP-independent periplasmic (TRAP) transporter permease is the membrane component of a TRAP tranporter, a substrate-binding protein (SBP)-dependent secondary transporter with similarity to C4-dicarboxylate TRAP transporter permease protein DctM

In some species, the 12-transmembrane spanning and 4-transmembrane spanning components of tripartite ATP-independent periplasmic (TRAP)-type transporters are fused. This model describes such transporters, found in the Archaea and in Bacteria.
