摘要：
Transcription from some sporulation-specific promoters of Bacillus subtilis is dependent on synthesis of pro-sigma(E) and its conversion to sigma(E) by proteolysis. Certain mutations in the precursor region of sigE, the gene encoding pro-sigma(E), apparently allow the mutant sigE products to be active as sigma-factors without being proteolysed in the normal way.
