Mutations in the precursor region of a Bacillus subtilis sporulation sigma factor.

RESUMO
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.
