Expression of representative class I, class II, class III, and class IV flagellar promoters in the flhG mutant V. cholerae strain. V. cholerae strains KKV598 (wild type) and KKV1701 (flhG) were transformed with the plasmids pKEK73 (flrAp-lacZ), pKEK72 (flrBp-lacZ), pKEK80 (flaAp-lacZ), pKEK331 (flgKp-lacZ), pKEK79 (flaBp-lacZ), pKEK76 (flaCp-lacZ), pKEK77 (flaDp-lacZ) and pKEK81 (flaEp-lacZ). β-Galactosidase activity was assayed during logarithmic growth in LB on the first and second days after transformation of the flhG mutant. Assays were performed in triplicate, and standard deviations are shown.
