Riboswitches are often conceptually divided into two parts: an aptamer and an expression platform. The aptamer directly binds the small molecule, and the expression platform undergoes structural changes in response to the changes in the aptamer. The expression platform is what regulates gene … Visa mer In molecular biology, a riboswitch is a regulatory segment of a messenger RNA molecule that binds a small molecule, resulting in a change in production of the proteins encoded by the mRNA. Thus, an mRNA that contains … Visa mer Prior to the discovery of riboswitches, the mechanism by which some genes involved in multiple metabolic pathways were regulated remained mysterious. Accumulating evidence increasingly suggested the then-unprecedented idea that the mRNAs … Visa mer Riboswitches demonstrate that naturally occurring RNA can bind small molecules specifically, a capability that many previously believed was the domain of proteins or … Visa mer Since riboswitches are an effective method of controlling gene expression in natural organisms, there has been interest in engineering artificial riboswitches for industrial and … Visa mer The following is a list of experimentally validated riboswitches, organized by ligand. • Cobalamin riboswitch (also B12-element), which binds either Visa mer Riboswitches have been also investigated using in-silico approaches. In particular, solutions for riboswitch prediction can be divided into two wide categories: • riboswitch … Visa mer Riboswitches could be a target for novel antibiotics. Indeed, some antibiotics whose mechanism of action was unknown for decades have … Visa mer Webb5 sep. 2013 · Riboswitches fold into complex three-dimensional structures in order to perform their regulatory functions. Structural analyses on riboswitches have revealed that they are assembled from motifs or structural elements that have been observed in other functional RNA molecules [10], [11].
