The levanase operon in Bacillus subtilis is expressed from a -12, -24 promoter and transcription is stimulated by the regulator LevR, which contains a domain homologous with the central domain of the NifA and NtrC family of regulators. We isolated mutants defective in the expression of the levanase operon. These strains contain mutations that define a gene, called sigL, located between cysB and sacB on the genetic map. The sigL gene was cloned and sequenced. It encodes a polypeptide containing 4 ...[more]
