Iron-containing transcription factors and their roles as sensors
Abstract
Iron-binding transcription factors are widespread throughout the bacterial world and to date are known to bind several types of cofactors, such as Fe2+, heme, or iron-sulfur clusters. The known chemistry of these cofactors is exploited by transcription factors, including Fur, FNR, and NsrR, to sense molecules such as Fe2+, gases (e.g. oxygen and nitric oxide), or reactive oxygen species. New structural data and information generated by genome-wide analysis studies have provided additional details about the mechanism and function of iron-binding transcription factors that act as sensors.

Further, the effects of Fe2+-Fur binding to DNA and the amino acids important for this interaction were investigated.
