Notes

[back to top]


fis transcription is supercoiling-dependent. Overexpression causes filamentous biofilm formation. Decreased levels of Fis inhibit open complex formation, inhibiting oriC unwinding by blocking IHF and DnaA low affinity binding sites. Polyamine modulon. Mutations affect chromosomal supercoliing.[4]
