Purine sensing by riboswitches [PDF]
Structured mRNA elements called riboswitches control gene expression by binding to small metabolites. Over a dozen riboswitch classes have been characterized that target a broad range of molecules and vary widely in size and secondary structure. Four of the known riboswitch classes recognize purines or modified purines.

Tetracycline aptamer-controlled regulation of pre-mRNA splicing in yeast [PDF]
Splicing of pre-mRNA is a critical step in mRNA maturation and disturbances cause several genetic disorders. We apply the synthetic tetracycline (tc)-binding riboswitch to establish a gene expression system for conditional tc-dependent control of pre ...

Comparative study between transcriptionally- and translationally-acting adenine riboswitches reveals key differences in riboswitch regulatory mechanisms. [PDF]
Many bacterial mRNAs are regulated at the transcriptional or translational level by ligand-binding elements called riboswitches. Although they both bind adenine, the adenine riboswitches of Bacillus subtilis and Vibrio vulnificus differ by controlling ...

Thermodynamic characterization of an engineered tetracycline-binding riboswitch [PDF]
Riboswitches reflect a novel concept in gene regulation that is particularly suited for technological adaptation. Therefore, we characterized thermodynamically the ligand binding properties of a synthetic, tetracycline (tc)-binding RNA aptamer, which ...

Structure of a rare non-standard sequence k-turn bound by L7Ae protein [PDF]
Kt-23 from Thelohania solenopsae is a rare RNA kink turn (k-turn) where an adenine replaces the normal guanine at the 2n position. L7Ae is a member of a strongly conserved family of proteins that bind a range of k-turn structures in the ribosome, box C/D

A critical base pair in k-turns that confers folding characteristics and correlates with biological function [PDF]
Kink turns (k-turns) are widespread elements in RNA that mediate tertiary contacts by kinking the helical axis. We have found that the ability of k-turns to undergo ion-induced folding is conferred by a single base pair that follows the conserved A·G ...

Affinity-Based Profiling of the Flavin Mononucleotide Riboswitch [PDF]
[Image: see text] Riboswitches are structural RNA elements that control gene expression. These naturally occurring RNA sensors are of continued interest as antibiotic targets, molecular sensors, and functional elements of synthetic circuits.

A novel riboswitch classification based on imbalanced sequences achieved by machine learning.
Riboswitch, a part of regulatory mRNA (50-250nt in length), has two main classes: aptamer and expression platform. One of the main challenges raised during the classification of riboswitch is imbalanced data.

Synthetic riboswitches can be used as chemical gene switches in cell-free protein synthesis systems. We provide a current perspective on the state of cell-free riboswitch technologies and their future directions.
