NprR, a moonlighting quorum sensor shifting from a phosphatase activity to a transcriptional activator

November 5, 2016

This article comments on work published by Perchat et al. (PLoS Pathog, 2016), which demonstrates that, in the absence of the signaling peptide NprX, the sensor NprR is a dimer, which negatively controls sporulation in Bacillus thuringiensis, independently of its transcription factor activity.
