proteopedia linkproteopedia link | FIS protein (Factor for Inversion Stimulation) or DNA-binding protein Fis is a regulatory protein in E. coli that activates ribosomal RNA transcription by binding to RNA promoter and enhances transcription by 5 to 10-fold. FIS binds to a sequence which stimulates hin-mediated DNA inversion and causes DNA bending. FIS affects the bacterial chromosome structure and the initiation of DNA replication. FIS exhibits autoregulation. It is abundant during E. coli exponential growth in rich medium and scarce during the stationary phase[1].
