Sigma M, an ECF RNA polymerase sigma factor of Bacillus subtilis 168, is essential for growth and survival in high concentrations of salt.

Molecular microbiology - 1 Apr 1999

Horsburgh M J, Moir A

Abstract excerpt

The Bacillus subtilis 168 genome encodes seven extracytoplasmic function (ECF) RNA polymerase sigma factors of unknown physiological function. The sigM(yhdM) gene, encoding an ECF sigma factor sigma M, is essential for growth and survival in nutrient broth (NB) containing 1.4 M NaCl. Strains insertionally inactivated in the sigM gene form aberrantly shaped cells, which swell and lyse spontaneously during growth...
