Protein
C4-dicarboxylate transport protein
Organism
Sinorhizobium fredii (strain NBRC 101917 / NGR234)
Function
Responsible for the transport of dicarboxylates such as succinate, fumarate, and malate from the periplasm across the inner membrane. This transport system plays an essential role in the energy supply of tropical rhizobium-legume symbionts.
