Role of yceA-cybB-yceB operon in oxidative stress tolerance, swimming motility and antibiotic susceptibility of Stenotrophomonas maltophilia.

The evidence strongly supports the view that the physiological function of the yceA-cybB-yceB operon is to alleviate oxidative stress. The operon provides an additional example that oxidative stress alleviation systems can cross-protect S. maltophilia from antibiotics.
