Genetic analysis of an important oxidative stress locus in the anaerobe Bacteroides fragilis.

Gene - 16 Oct 2003

Herren Christopher D, Rocha Edson R, Smith C Jeffrey

Abstract excerpt

The obligate anaerobe, Bacteroides fragilis, is a highly aerotolerant intestinal tract organism that has evolved a complex oxidative stress response (OSR). The redox regulator OxyR controls several OSR genes (katB, dps, and ahpC), but there is little else known about other genes it regulates. To identify additional genes in the OxyR regulon, two-dimensional gel electrophoresis was used to isolate proteins from a...
