摘要：

A mutation, bofC1, that restores sigma(K) activation in Bacillus subtilis strains unable to produce active sigma(G) has been identified. This mutation defines a new sporulation gene, bofC, that has been cloned and sequenced and encodes a 19 kDa protein. bofC is transcribed in the forespore by RNA polymerase associated with the transcription factors sigma(F) (E sigma(F)) and sigma(G) (E sigma(G)). BofC acts negatively on SpoIVB and the results described suggest that BofC regulates SpoIVB activity and its intercompartmental signalling role in the sigma(K) checkpoint.
