== Publication Abstract from PubMed ==
Previously, we determined the crystal structure of apo-TpMglB-2, a D-glucose-binding component of a putative ABC transporter from the syphilis spirochete Treponema pallidum. The protein had an unusual topology for this class of proteins, raising the question of whether the D-glucose-binding mode would be different in TpMglB-2. Here, we present the crystal structures of a variant of TpMglB-2 with and without D-glucose bound. The structures demonstrate that, despite its aberrant topology, the protein undergoes conformational changes and binds D-glucose similarly to other Mgl-type proteins, likely facilitating D-glucose uptake in T. pallidum.
