A regulatory protein that binds to specific sites on DNA and stimulates transcription; involved in positive control
Activator protein
A mechanism for controlling gene expression; typically transcription is terminated after initiation but before a full length mRNA is produced
Attenuation
Small signal molecule that takes part in quorum sensing
Autoinducer
The suppression of alternative catabolic pathways by a preferred source of carbon and energy
catabolite repression
A regulatory nucleotide that participates in catabolite repression
Cyclic Amp
Proteins induced by high temperature (or certain other stresses) that protect against high temperature, especially by refolding partially denatured proteins by degrading them
Heat shock proteins
response to high temperature that includes the synthesis of heat shock proteins together with other changes in gene expression
Heat shock response
production of an enzyme in response to a signal (often the presence of the substrate of the enzyme)
Induction
a mechanism for regulating gene expression in which a repressor protein prevents transcription of genes
negative control
a mechanism for regulating gene expression in which a repressor protein prevents transcription of genes
Negative control
an RNA molecule that is not translated into protein
Noncoding RNA
one or more genes transcribed into a single RNA and under the control of a single regulatory site
Operon
a mechanism for regulating gene expression in which an activator protein functions to promote transcription of genes
positive control
a regulatory system that monitors the population level and controls gene expression based on cell denisty
quorum sensing
a nucleotide that functions as a signal rather than being incorporated into RNA or DNA
Regulatory nucleotide
a series of operons controlled as a unit
regulon
preventing the synthesis of an enzyme in response to a signal
repression
a regulatory protein that binds to specific sites on dNA and blocks transcription; involved in negative control
repressor protein
one of the members of a two component system; a protein that is phosphorylated by a sensor kinase adn then acts as a regulator, often by bindign to dna
response regulator protein
one of the members of a two-component system; a protein that phosphorylates itself in response to an external signal and then transferes teh phosphoryl group to a response regulator protein
sensor kinase protein
two component regulatory system
signal transduction
a global regulatory control is activated by amino acid starvation or energy definciency
stringent response
a regulatory system consisting of two proteins; a sensor kinase and a response regulator
