Part of the high-affinity ABC transporter complex FrcBCA involved in fructose uptake. Is also a high-affinity transporter for ribose and mannose (PubMed:11466273). Responsible for energy coupling to the transport system (Probable). ATP + D-fructose(out) + H2O = ADP + D-fructose(in) + H(+) + phosphate The complex is composed of two ATP-binding proteins (FrcA), two transmembrane proteins (FrcC) and a solute-binding protein (FrcB). Belongs to the ABC transporter superfamily.
