Riboswitch diversity and distribution [PDF]
Riboswitches are commonly used by bacteria to detect a variety of metabolites and ions to regulate gene expression. To date, nearly 40 different classes of riboswitches have been discovered, experimentally validated, and modeled at atomic resolution in complex with their cognate ligands.

RNA folding kinetics control riboswitch sensitivity in vivo
Riboswitches are ligand-responsive gene-regulatory RNA elements that perform key roles in maintaining cellular homeostasis. Understanding how riboswitch sensitivity to ligand (EC50) is controlled is critical to explain how highly conserved aptamer ...

Using a Riboswitch Sensor to Detect Co2+/Ni2+ Transport in E. coli
Intracellular concentrations of essential mental ions must be tightly maintained to avoid metal deprivation and toxicity. However, their levels in cells are still difficult to monitor. In this report, the combination of a Co2+Ni2+-specific riboswitch and

PATTERNA: transcriptome-wide search for functional RNA elements via structural data signatures. [PDF]
Establishing a link between RNA structure and function remains a great challenge in RNA biology. The emergence of high-throughput structure profiling experiments is revolutionizing our ability to decipher structure, yet principled approaches for ...

Evaluating riboswitch optimality
Riboswitches are RNA elements that recognize diverse chemical and biomolecular inputs, and transduce this recognition process to genetic, fluorescent, and other engineered outputs using RNA conformational changes. These systems are pervasive in cellular biology and are a promising biotechnology with applications in genetic regulation and biosensing ...

Singlet glycine riboswitches bind ligand as well as tandem riboswitches [PDF]
The glycine riboswitch often occurs in a tandem architecture, with two ligand-binding domains (aptamers) followed by a single expression platform. Based on previous observations, we hypothesized that “singlet” versions of the glycine riboswitch, which contain only one aptamer domain, are able to bind glycine if appropriate structural contacts are ...

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

Thiamine Acquisition Strategies Impact Metabolism and Competition in the Gut Microbe Bacteroides thetaiotaomicron. [PDF]
Thiamine (vitamin B1) is an essential cofactor for all organisms. Humans primarily acquire thiamine through their diet, and thiamine deficiencies have adverse neurological effects.
