FIG. 4.
CysJ operates within the MoCo-dependent pathway of base analog detoxification (A) and within the ycbX-dependent pathway (B). Shown are results of survival tests after a 2-h exposure to the indicated concentrations of HAP in liquid medium. Strains used were NR16523 (moaE), NR16757 (cysJ moaE), NR15871 (yiiM), NR15873 (ycbX), NR16043 (cysJ), NR16087 (cysJ ycbX), and NR16085 (cysJ yiiM). See Materials and Methods for further details.
