FIG. 5.
Swimming characterization of different strains expressing the motBsup alleles. (A) Swimming assay of the control strains WS8, FS4 (ΔmotB1::Kan), and FS5 (ΔmotB1::Kan ΔfliL3::aadA). Also included are FS4 and FS5 expressing the motB wild-type allele from pRK415. (B) Swimming of the double mutant FS5 (ΔmotB1::Kan ΔfliL3::aadA) expressing the motBsup alleles from the lac promoter of pRK415. (C) Swimming of FS4 (ΔmotB1::Kan) expressing the motBsup alleles from pRK415. (D) Swimming of the suppressor mutants expressing the fliL wild-type allele from pRK415.
