Abstract: It has been discovered that certain natural mRNAs serve as metabolite-sensitive genetic switches wherein the RNA directly binds a small organic molecule. This binding process changes the conformation of the mRNA, which causes a change in gene expression by a variety of different mechanisms. Modified versions of these natural “riboswitches” (created by using various nucleic acid engineering strategies) can be employed as designer genetic switches that are controlled by specific effector compounds. Such effector compounds that activate a riboswitch are referred to herein as trigger molecules. The natural switches are targets for antibiotics and other small molecule therapies.

Abstract: Riboswitches are structural elements in mRNA that change state when bound by a trigger molecule, and are thus able to regulate gene expression. They can be dissected into two separate domains: one that selectively binds the target (aptamer domain) and another that influences genetic control (expression platform domain). Bacterial glycine riboswitches consist of two tandem aptamer domains which cooperatively bind glycine to regulate the expression of downstream genes. These natural switches are targets for antibiotics and other small molecule therapies. Modified versions of these natural riboswitches can be employed as designer genetic switches that are controlled by specific effector compounds. Disclosed are isolated and recombinant riboswitches, and compositions and methods for selecting and identifying compounds that can activate, inactivate, or block a riboswitch.
