    “…In Bacillus subtilis, transcription of the tryptophan biosynthetic operon is regulated by an attenuation mechanism. When intracellular tryptophan levels are high, the TRAP protein binds to the 5′ leader region of the nascent trp mRNA and induces transcription termination prior to the structural genes. …”

    “…To gain insight into the origin of enterotoxin expression heterogeneity in different strains, the architecture and role of 5′ intergenic regions (5′ IGRs) upstream of the nhe and hbl operons was investigated. In silico comparison of 142 strains of all seven phylogenetic groups of B. cereus sensu lato proved the presence of long 5′ IGRs upstream of the nheABC and hblCDAB operons, which harbor recognition sites for several transcriptional regulators, including the virulence regulator PlcR, redox regulators ResD and Fnr, the nutrient-sensitive regulator CodY as well as the master regulator for biofilm formation SinR. …”

    “…Different relative expression behaviours are proven here for arcR (ACME) and the arc (ACME) operon compared to the constitutive ones. We also show that the artificially expressed recombinant ArcR(ACME) protein binds to the promoter region of the arc (ACME) operon; this mechanism can be related to a positive feedback model, which may be responsible for increased anaerobic survival of the USA300 clone during infection-related processes.…”
