Extended Data Table 2. RMSD of overall structure (blue) and TMD region (orange).
Superposition was performed at backbone level and RMSD was calculated at the Cα level. Nterm elbow and Cterm zipper helices were excluded from the superimposition and RMSD calculation. RMSD values of 0.64 Å and 0.70 Å show that the OFopen and OFoccluded conformations determined from the TmrABATP-Vi and TmrAEQBATP datasets, respectively, are very similar.
