RT   "Fructose uptake in Sinorhizobium meliloti is mediated by a high-affinity
RT   ATP-binding cassette transport system.";
RL   J. Bacteriol. 183:4709-4717(2001).
CC   -!- FUNCTION: Part of the high-affinity ABC transporter complex FrcBCA
CC       involved in fructose uptake. Is also a high-affinity transporter for
CC       ribose and mannose. Binds fructose, ribose and mannose.
CC       {ECO:0000269|PubMed:11466273}.
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (FrcA),
CC       two transmembrane proteins (FrcC) and a solute-binding protein (FrcB).
CC       {ECO:0000305|PubMed:11466273}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000269|PubMed:11466273}.
CC   -!- INDUCTION: Induced by fructose. {ECO:0000269|PubMed:11466273}.
CC   -!- SIMILARITY: Belongs to the bacterial solute-binding protein 2 family.
CC       {ECO:0000305}.
