Multiple SigB homologues govern the transcription of the ssgBp promoter in the sporulation-specific ssgB gene in Streptomyces coelicolor A3(2)
{{output}}
Unlike Bacillus subtilis, Streptomyces coelicolor contains nine SigB homologues of the stress-response sigma factor SigB. By using a two-plasmid system, we previously identified promoters recognized by these sigma factors. Almost all promoters were recognized ... ...
