A threshold mechanism governing activation of the developmental regulatory protein sigma F in Bacillus subtilis.

The Journal of biological chemistry - 9 Apr 2004

Carniol Karen, Eichenberger Patrick, Losick Richard

Abstract excerpt

The RNA polymerase sigma factor sigma(F) is a developmental regulatory protein that is activated in a cell-specific manner following the formation of the polar septum during the process of spore formation in the bacterium Bacillus subtilis. Activation of sigma(F) depends on the membrane-bound pho...
