FIG. 3.

Expression of lysine decarboxylase of the wild type (AR) (WT), soxR mutant SR1, cadC mutant JR309, and cadC soxR double mutant CSR1 after growth transition to LBS (pH 7.5) supplemented with 3 mM MV. Lysine decarboxylase activity was examined with cells harvested at 0 h, 2 h, 4 h, and 6 h after transfer. CAT activity from pCB367 was determined at the time points indicated. The error bars correspond to the standard deviations of the means, and CAT activity data represent means ± standard deviations.
