Allosteric mechanism of induction of CytR-regulated gene expression. Cytr repressor-cytidine interaction

Autor: C S, Barbier, S A, Short, D F, Senear

Publikováno v: The Journal of biological chemistry. 272(27)

Transcription from cistrons of the Escherichia coli CytR regulon is activated by E. coli cAMP receptor protein (CRP) and repressed by a multiprotein complex composed of CRP and CytR. De-repression results when CytR binds cytidine. CytR is a homodimer

Characterization of cytR mutations that influence oligomerization of mutant repressor subunits

Autor: C S Barbier, S A Short

In Escherichia coli, the transport and catabolism of nucleosides require expression of the genes composing the CytR regulon. The role of the CytR repressor in transcriptional regulation has been examined through a study of mutant CytR proteins. Two i

Amino acid substitutions in the CytR repressor which alter its capacity to regulate gene expression

Autor: C S Barbier, S A Short

In Escherichia coli, transport and catabolism of nucleosides require expression of the genes composing the CytR regulon. Transcription initiation of cistrons in this gene family is activated by cyclic AMP-catabolite activator protein (cAMP-CAP), repr

Identification of the Escherichia coli deoR and cytR gene products

Autor: J T Singer, C S Barbier, S A Short

Publikováno v: Journal of Bacteriology. 163:1095-1100

The protein products encoded by the Escherichia coli deoR and cytR structural genes have been identified based on results obtained from E. coli maxicells harboring (i) recombinant plasmids carrying wild-type deoR and cytR genes, (ii) deletion derivat
