== 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.

Function

SPOVT_BACSU Transcriptional factor that regulates positively or negatively the expression of a large number of forespore-specific sigma G-dependent genes. May provide a mechanism of feedback control that is important for forespore development (PubMed:8755877). SpoVT levels during spore formation have a major impact on the germination and the resistance of the resultant spores (PubMed:22522895).[1] [2]

Evolutionary Conservation
