Cu-sensitive promoter

Promoter from the copper-sensitive CusR/CusS two component signal system. (E.Coli). This nucleotide sequence is believed to be able to bind with phosphorylated CusR transcription factor in E.coli. CusR protein is phosphorylated by CusS transmembrane protein in a case of high extracellular concentration of copper ions. After phosphorylation CusR interacts with described DNA sequence and activates the transcription of CusA, CusB, CusC and CusF genes coding the proteins of copper metabolic system. Was used by Saint-Petersburg Team for constructing a copper biosensor system
