Microtubule-stimulated ATPase activities of Tetrahymena kinesin-9 dimers. (a, b) Data (circles with error bars: SD [n = 4]) for TtK9A and TtK9B1 are fitted to Michaelis–Menten model (lines) with \({k}_{\text{cat}}\) values of 0.22 ± 0.01 s−1 and 2.2 ± 0.1 s−1 per dimer and \({K}_{0.5,\text{ MT}}\) of 0.7 ± 0.1 and 0.4 ± 0.1 μM, respectively (mean ± SEM).
