Activation of FNR-dependent transcription by iron: an in vitro switch for FNR.

abstract：:During protein synthesis, elongation factor G (EFG) participates at the steps of translocation and ribosome recycling. Fusidic acid (FA) is a bacteriostatic antibiotic, which traps EFG on ribosomes, stalling them on mRNAs. How the bacterial susceptibility to FA is determined, and which of the two functions of EFG (tra...
