Fig. 6.

Schematic representation of enzyme-inhibitor protein complex formation for the different truncated mutants. (a) MtDUT^WT-Stl^WT complex formation. (b) MtDUT^WT–Stl^NT complex formation. (a, b) The representations of the individual molecules are similar to the ones as on Figure S2. The protein-protein complexes are shown as the complexes of the individual proteins, which representations are based on MtDUT^WT-Stl^NT structural model (PDB ID: 8P8O), the exact conformation of the proteins and their binding stoichiometry are not taken into account. The magnitude of k_on and k_off values determined in the BLI measurements are represented as green and red arrows, respectively. Please note, that the dimensions of k_on and k_off values are different. Therefore, only the same kind of rate constants from the different complex formation reactions are comparable with each other.
