Abstract

A mutation, , that restores σ activation in strains unable to produce active σ has been identified. This mutation defines a new sporulation gene, , that has been cloned and sequenced and encodes a 19 kDa protein. is transcribed in the forespore by RNA polymerase associated with the transcription factors σ (Eσ) and σ (Eσ). BofC acts negatively on SpolVB and the results described suggest that BofC regulates SpolVB activity and its intercompartmental signalling role in the σ checkpoint
