==Crystal Structure of the Glycerol-3-Phosphate Transporter from E.Coli==

The major facilitator superfamily represents the largest group of, secondary membrane transporters in the cell. Here we report the 3.3, angstrom resolution structure of a member of this superfamily, GlpT, which, transports glycerol-3-phosphate into the cytoplasm and inorganic phosphate, into the periplasm. The amino- and carboxyl-terminal halves of the protein, exhibit a pseudo two-fold symmetry. Closed off to the periplasm, a, centrally located substrate-translocation pore contains two arginines at, its closed end, which comprise the substrate-binding site. Upon substrate, binding, the protein adopts a more compact conformation. We propose that, GlpT operates by a single-binding site, alternating-access mechanism, through a rocker-switch type of movement.
