Abstract excerpt
We isolated a temperature-sensitive sporulation defective mutant of the sigA gene, encoding a major sigma factor, sigma(A) protein, in Bacillus subtilis, and designated it as sigA21. The sigA21 mutation caused a single-amino acid substitution, E314K, in region 4 of the sigma(A) protein. In this mutant, expression of the spoIIG gene, whose transcription depends on both sigma(A) and the phosphorylated Spo0A...
