Figure 3From: Crystal structures of an Extracytoplasmic Solute Receptor from a TRAP transporter in its open and closed forms reveal a helix-swapped dimer requiring a cation for α-keto acid bindingOverall structure of TakP. A: View of the TakP monomer colored as a ramp from blue to red from the N- to C-Terminus. B: View of the TakP monomer with colors according to the different structural domains. C, D: Two different orientations of the TakP dimer. Both monomers are colored as in B but one is slightly transparent and result in a paler coloring.Back to article page
