Function

[ABRB_BACSU] Ambiactive repressor and activator of the transcription of genes expressed during the transition state between vegetative growth and the onset of stationary phase and sporulation. It controls the expression of genes spovG and tycA. AbrB binds to the tycA promoter region at two A- and T-rich sites, it may be the sole repressor of tycA transcription.^[1]

Publication Abstract from PubMed

Understanding the DNA recognition and binding by the AbrB-like family of transcriptional regulators is of significant interest since these proteins enable bacteria to elicit the appropriate response to diverse environmental stimuli. Although these "transition-state regulator" proteins have been well characterized at the genetic level, the general and specific mechanisms of DNA binding remain elusive. We present RDC-refined NMR solution structures and dynamic properties of the DNA-binding domains of three Bacillus subtilis transition-state regulators: AbrB, Abh, and SpoVT. We combined previously investigated DNase I footprinting, DNA methylation, gel-shift assays, and mutagenic and NMR studies to generate a structural model of the complex between AbrBN(55) and its cognate promoter, abrB8. These investigations have enabled us to generate a model for the specific nature of the transition-state regulator-DNA interaction, a structure that has remained elusive thus far.
