Obg, an essential GTP binding protein of Bacillus subtilis, is necessary for stress activation of transcription factor sigma(B).

Journal of bacteriology - 1 Aug 1999

Scott J M, Haldenwang W G

Abstract excerpt

sigma(B), the general stress response sigma factor of Bacillus subtilis, is activated when intracellular ATP levels fall or the bacterium experiences environmental stress. Stress activates sigma(B) by means of a collection of regulatory kinases and phosphatases (the Rsb proteins), which catalyze the release of sigma(B) from an anti-sigma factor inhibitor. By using the yeast dihybrid selection system to identify...
