CC -!- FUNCTION: Uptake of citrate across the boundary membrane with the
CC concomitant transport of protons into the cell (symport system)
CC (Probable). Allows the utilization of citrate as a sole source of
CC carbon and energy upon expression in E.coli (PubMed:1718953).
CC {ECO:0000269|PubMed:1718953}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305|PubMed:1718953};
CC Multi-pass membrane protein {ECO:0000305|PubMed:1718953}.
CC -!- SIMILARITY: Belongs to the major facilitator superfamily. Metabolite:H+
CC Symporter (MHS) family (TC 2.A.1.6) family. {ECO:0000305}.
