In-silico tertiary structure of a viral SMR homodimer. (A) Side view of the homodimer of MarDSR188 encoded by Dashavirus strain R2023E. The four TM helices, N-terminus and C-terminus of a monomer are label. (B) Top view of the viral SMR structures, with red spheres indicating the positions of residues are similar to that of which were reported to be implicated in substrate binding and transport in E. coli SMR13. One monomer is rendered in color gradient with label in bold and the other one is shown in gray.
