THE STRUCTURE OF BACILLUS SUBTILIS RBSD COMPLEXED WITH D-RIBOSE

Overview

RbsD is the only protein whose biochemical function is unknown among the, six gene products of the rbs operon involved in the active transport of, ribose. FucU, a paralogue of RbsD conserved from bacteria to human, is, also the only protein whose function is unknown among the seven gene, products of the l-fucose regulon. Here we report the crystal structures of, Bacillus subtilis RbsD, which reveals a novel decameric toroidal assembly, of the protein. Nuclear magnetic resonance and other studies on RbsD, reveal that the intersubunit cleft of the protein binds specific forms of, d-ribose, but it does not have an enzyme activity toward the sugar., Likewise, FucU binds l-fucose but lacks an enzyme activity toward this, sugar. We conclude that RbsD and FucU are cytoplasmic sugar-binding, ... [(full description)]
