But other operons respond to the presence of their small molecule signal ligand; that is, they are negatively regulated by a repressor protein, but they are inducible (i.e., they can be turned on ...

Molecules can interfere with RNA polymerase binding. An inactive repressor protein (blue) can become activated by another molecule (red circle). This active repressor can bind to a region near the ...

This specificity narrows the ability to use the LacI system in cases where researchers can’t insert this sequence, prompting a search for a more flexible repressor protein that can recognize more ...

Rheumatoid arthritis (RA) is an inflammatory arthritis characterized by chronic joint inflammation, cartilage degradation, and bone erosion.

This DNA-binding protein was previously known to have played ... More information: KorB switching from DNA-sliding clamp to repressor mediates long-range gene silencing in a multi-drug resistance ...
