Bottom row, thermophilic MjFtsZ. The kinetic rates of GTP hydrolysis, <i>k<sub>cat</sub></i> (A and C), and filament depolymerization, <i>k<sub>depol</sub></i> (B and D), are plotted as a function of temperature. The apparent enthalpies (Δ<i>H</i><sup>0‡</sup>) and entropies (Δ<i>S</i><sup>0‡</sup>) of the transition state were calculated by nonlinear regression using <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0185707#pone.0185707.e006" target="_blank">Eq 4</a> (solid lines), and the best-fit values are reported in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0185707#pone.0185707.t003" target="_blank">Table 3</a>.</p>
