Fig. 7. Swim speed of reactivated models. Mutant cells were harvested for analysis from growth media containing paromomycin and cadmium (+ drug) or from growth media in which these selective agents were absent (– drug). Detergent-extracted models of wild type (CU427.4) and mutant (DYH7neo3) were prepared. Forward swimming resumed when cell models of wild type and mutant were reactivated in the presence of 1 mM MgATP. Reactivated mutant models displayed a slower swim speed than that observed for wild-type models. Each bar represents the mean ± s.d. of three trials of 50-cell measurements.
