    ..The properties of the two transport systems for arabinose are compared with those of the genetically and biochemically distinct transport systems for galactose, GalP and MglP. It appears that AraE is analogous to GalP, and AraF to MglP. ..

    ..Therefore, L-arabinose-binding protein-mediated transport appears to require only two inducible membrane-associated components (araG and araH) in addition to the binding protein (araF).

    ..The 3' end of the otsB coding region overlaps the 5' end of the otsA coding region by 23 nucleotides. The araH gene is located directly upstream from otsBA, and otsB may be identical to pexA.
