Essential internal promoter in the spoIIIA locus of Bacillus subtilis.


The Bacillus subtilis spoIIIA locus encodes eight proteins, SpoIIIAA to SpoIIIAH, which are expressed in the mother cell during endospore formation and which are essential for the activation of sigma(G) in the forespore. Complementation studies indicated that this locus may be transcribed from two promoters, one promoter upstream from the first gene and… (More)
