One crystal was used to collect diffraction datasets for each structure, except in the EAAT1cryst UCPH101 and TFB-TBOA bound structure, where datasets from three crystals were merged.
5% of reflections were used for calculations of Rfree, except for the EAAT1cryst UCPH101-TBOATFB bound structure where 10% was used due to the lower number of total reflections.
