[[http://www.uniprot.org/uniprot/SP0A_BACSU SP0A_BACSU]] May play the central regulatory role in sporulation. It may be an element of the effector pathway responsible for the activation of sporulation genes in response to nutritional stress. Spo0A may act in concert with Spo0H (a sigma factor) to control the expression of some genes that are critical to the sporulation process. Repressor of abrB, activator of the spoIIa operon. Binds the DNA sequence 5'-TGNCGAA-3' (0A box).

== Publication Abstract from PubMed ==
Sporulation in Bacillus species, the ultimate bacterial adaptive response, requires the precisely coordinated expression of a complex genetic pathway, and is initiated through the accumulation of the phosphorylated form of Spo0A, a pleiotropic response regulator transcription factor. Spo0A controls the transcription of several hundred genes in all spore-forming Bacilli including genes for sporulation and toxin regulation in pathogens such as Bacillus anthracis. The crystal structure of the effector domain of Spo0A from Bacillus subtilis in complex with its DNA target was determined. In the crystal lattice, two molecules form a tandem dimer upon binding to adjacent sites on DNA. The protein:protein and protein:DNA interfaces revealed in the crystal provide a basis for interpreting the transcription activation process and for the design of drugs to counter infections by these bacteria.
