MT lattice parameters obtained in this study are reported alongside previously published values for reference. Expanded lattices are in blue (GMPCPP and undecorated catalytically inactive mutants), presumed transition state MTs (GDP+Pi or GTPγS) are colored in green, and compacted lattices are shaded in red (GDP state or catalytically inactive mutants + EB3). NA signifies cases in which intradimer or interdimer values were not reported due to mixing of α/β-tubulin subunits or in which resolution was too low to accurately determine the values.
