The β-tubulin with GDP and paclitaxel was extracted from tubulin of Bos taurus (PDB entry 1JFF).
In this respect, the crystal structures of tubulin (PDB entry 1JFF) and Bs FtsZ (PDB entry 2RHL) were superimposed on each other and structurally aligned using PyMol to determine the residues of Bs FtsZ that were in the proximity of the paclitaxel binding site in tubulin.

S4 B. The DireX program ( Wang and Schröder, 2012 ) was used for flexible fitting of the crystal structure of the dynein MTBD (PDB ID: 3KVH ; Kon et al., 2012 ) and tubulin dimer (PDB ID: 1JFF ; Löwe et al., 2001 ) into the map.
Note: In this paper, we adopted numbering of amino acid residues for S. cerevisiae yeast tubulin, which is slightly different from that of the Sus scrofa pig tubulin used in the PDB file 1JFF ( Fig. 1 B ).

Also all designed structures as well as griseofulvin were docked into the active site of microtubule (1JFF), using Autodock program.
Because the griseofulvin binding site partially overlaps with the paclitaxel site in tubulin [ 30 ], therefore, microtubul complexed with paclitaxel (1JFF) was obtained from Protein Data Bank for docking studies.
Autodock program used and all designed structures as well as griseofulvin were docked into the active site of 1JFF.
Modeling All the compounds ( Table 2 ) as well as griseofulvin were docked into the active site of microtubule, which was obtained from Protein Data Bank (1JFF) using Autodock 4.2.
The microtubule complexed with paclitaxol was obtained from Protein Data Bank (1JFF).
To obtain a short segment of the MT wall, we fitted the crystal structure of the tubulin dimer (1JFF.
Computational Simulations Binding to the Taxane Binding Site The coordinates of the tubulin-taxane receptor-ligand complex were obtained from the PDB crystal structure 1JFF [ 34 ], which represents pa... litaxel co-crystallized with tubulin.
Next, the protonation state of ionizable residues in 1JFF was determined using PROPKA and hydrogen atoms added to obtain a complete αβ-tubulin heterodimer.
