TRAP C4-dicarboxylate transport system permease DctM subunit (IPR010656)

Short name: DctM

Overlapping homologous superfamilies


Domain relationships



This domain represents a conserved region located towards the N terminus of 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 [PMID: 11803016, PMID: 11524131]. Note that many family members are hypothetical proteins.
