Sigma factor displacement from RNA polymerase during Bacillus subtilis sporulation.

Journal of bacteriology - 1 Aug 1999

Ju J, Mitchell T, Peters H, Haldenwang W G

Abstract excerpt

As Bacillus subtilis proceeds through sporulation, the principal vegetative cell sigma subunit (sigma(A)) persists in the cell but is replaced in the extractable RNA polymerase (RNAP) by sporulation-specific sigma factors. To explore how this holoenzyme changeover might occur, velocity centrifugation techniques were used in conjunction with Western blot analyses to monitor the associations of RNAP with sigma(A)...
