WebApr 13, 2024 · Seven family members of metal-binding transcription factors have been identified in bacteria: ArsR-SmtB, NikR, DtxR, MerR, Fur, CopY, and CsoR-RcnR ( Osman and Cavet, 2010 ). Each family takes part in sensing a distinct group of metals. ArsR is a repressor protein belonging to the ArsR-SmtB family. WebMar 1, 2024 · The initiation of transcription in bacteria begins with the binding of RNA polymerase to the promoter in DNA.
