Gene expression in Escherichia coli is controlled by well-established mechanisms that activate or repress transcription. Here, we identify CedA as an unconventional transcription factor specifically associated with the RNA polymerase (RNAP) σ70 holoenzy

The synthesis of mRNA molecules byRNApolymerase II (RNAPII) is a multistep process requiring the interaction of numerous proteins with DNA in the region of the promoter (Chapter 23). However, before the expression of a gene can be initiated, thetranscription factor IID(TFIID) must bind to the...
GRF (General regulatory factor 2) or 14.3.3's are 30KDa proteins involved in protein interactions with target proteins containing phosphorylated target sites. Functions of 14.3.3's include acting as adaptors or scaffolds, stimulating protein-protein interaction, altering target protein activity, causing...
Understanding gene expression will require understanding where regulatory factors bind genomic DNA. The frequently used sequence-based motifs of protein-DNA binding are not predictive, since a genome contains many more binding sites than are actually bound and transcription factors of the same family sha...

Three main regulatory elements are required to control the GSR in α-proteobacteria: an EcfG-type ECF σ factor (G standing for GSR), its cognate anti-σ factor NepR and the response regulator PhyR4. In favourable growth conditions, EcfG is sequestered by NepR, thus preventing the ...
