The Ada regulon in E. coli is a well-characterized example of a group of genes involved in the adaptive response form of DNA repair. [6] Quorum sensing behavior in bacteria is a commonly cited example of a modulon or stimulon, [7] though some sources describe this type of intercellular auto-induction as a separate form of regulation. [1]
Enzyme induction is a process in which a molecule (e.g. a drug) induces (i.e. initiates or enhances) the expression of an enzyme. Enzyme inhibition can refer to the inhibition of the expression of the enzyme by another molecule; interference at the enzyme-level, basically with how the enzyme works.
Gene regulatory pathway. In genetics, a regulator gene, regulator, or regulatory gene is a gene involved in controlling the expression of one or more other genes. Regulatory sequences, which encode regulatory genes, are often at the five prime end (5') to the start site of transcription of the gene they regulate.
This set of predicted binding sites corresponds to 12,574 TF → gene regulatory interactions; this represents a recovery of 52% of the 1592 annotated regulatory interactions in the database for the 93 TFs for which RegulonDB has a position-weight matrix (PWM). If only TFs with a good-quality PWM are taken into account, the total number of ...
Index inducer or just inducer predictably induce metabolism via a given pathway and are commonly used in prospective clinical drug-drug interaction studies. [4] Strong, moderate, and weak inducers are drugs that decreases the AUC of sensitive index substrates of a given metabolic pathway by ≥80%, ≥50% to <80%, and ≥20% to <50% ...

Structure of a gene regulatory network Control process of a gene regulatory network. A gene (or genetic) regulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins which, in turn, determine the function of the cell.
The yeast two-hybrid and bacterial two-hybrid screen [42] investigate the interaction between artificial fusion proteins. They do not require isolation of proteins but rather use transformation to express proteins in bacteria or yeast. The cells are designed in a way that an interaction activates the transcription of a reporter gene or a ...
