[Study of the mechanism for regulating ribR gene activity in Bacillus subtilis].
Analysis of the phenotypic manifestation of inactivation of several genes from the ytlI-ytnM operon containing the ribR gene and results of Northern hybridization showed that the ribR gene does not have the self promoter and is transcribed from the main promoter of the ytlI-ytnM operon. Two sites of single nucleotide substitutions leading to derepresson of ribR gene were identified between the putative main promoter and transcription start of the ytlI-ytnM operon regulatory region.
