Identification and characterisation of thiamine pyrophosphate (TPP) riboswitch in Elaeis guineensis.
The oil palm (Elaeis guineensis) is an important crop in Malaysia but its productivity is hampered by various biotic and abiotic stresses. Recent studies suggest the importance of signalling molecules in plants in coping against stresses, which includes ...

A riboswitch-based inducible gene expression system for mycobacteria. [PDF]
Research on the human pathogen Mycobacterium tuberculosis (Mtb) would benefit from novel tools for regulated gene expression. Here we describe the characterization and application of a synthetic riboswitch-based system, which comprises a mycobacterial ...

Riboswitch RNAs regulate gene expression by conformational changes induced by environmental conditions and specific ligand binding. The guanidine-II riboswitch is proposed to bind the small molecule guanidinium and to subsequently form a kissing loop ...

Riboswitches are common cis-acting regulatory elements in bacteria. They are made of nascent RNA that changes its conformation in response to direct binding of cognate metabolites. The publication of five high-resolution crystal structures provides a comprehensive view of how riboswitches sense their ligands and points to new challenges in this ...

Riboswitch finder--a tool for identification of riboswitch RNAs [PDF]
We describe a dedicated RNA motif search program and web server to identify RNA riboswitches. The Riboswitch finder analyses a given sequence using the web interface, checks specific sequence elements and secondary structure, calculates and displays the energy folding of the RNA structure and runs a number of tests including this information to ...

A transient conformation facilitates ligand binding to the adenine riboswitch
Summary: RNAs adopt various conformations to perform different functions in cells. Incapable of acquiring intermediates, the key initiations of ligand recognition in the adenine riboswitch have not been characterized.

Magnesium ions mediate ligand binding and conformational transition of the SAM/SAH riboswitch
The SAM/SAH riboswitch binds S-adenosylmethionine (SAM) and S-adenosylhomocysteine (SAH) with similar affinities. Mg2+ is generally known to stabilize RNA structures by neutralizing phosphates, but how it contributes to ligand binding and conformational ...
