To kill but not be killed: a delicate balance
Abstract
Before launching a missile, it is necessary to design an efficient safety net for self-protection. In this issue of Cell, Ellermeier et al. (2006) describe the mechanism underlying a biological safety net for the soil bacterium Bacillus subtilis. This bacterium protects itself from a toxic protein it secretes by upregulating an immunity protein, which it does by sequestering a transcriptional repressor at the plasma membrane.
