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.

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.
