Subunit of: ribose ABC transporter

Subunit composition of ribose ABC transporter = [RbsA]2[RbsC]2[RbsB]
         ribose ABC transporter - putative ATP binding subunit = RbsA
         ribose ABC transporter - membrane subunit = RbsC
         ribose ABC transporter - putative periplasmic binding protein = RbsB

RbsACB is an ATP-dependent ribose transporter that is a member of the ATP-Binding Cassette (ABC) Superfamily of transporters [Park99]. Based on sequence similarity, RbsA is the ATP-binding constituent, RbsB is the periplasmic substrate-binding protein, and RbsC form the transmembrane constituent of the transporter [Park99]. Mutations in each of the components eliminated transport of ribose at external concentration of 1 μM, indicating that the components make up a transport system that is responsible for high-affinity ribose transport. However, these mutants are able to grow normally on high concentrations of the sugar, suggesting that there is at least a second, low-affinity transport system for ribose in E. coli [Iida84]. Hydrophobicity analysis has shown that RbsC contains six transmembrane helices, while alkaline phosphatase fusions and the use of inside-out vesicles with proteolysis have shown that the C and N termini are both on the cytoplasmic side of the membrane.
