Selecting RNA aptamers for synthetic biology: investigating magnesium dependence and predicting binding affinity. [PDF]

open access: yes, 2010
The ability to generate RNA aptamers for synthetic biology using in vitro selection depends on the informational complexity (IC) needed to specify functional structures that bind target ligands with desired affinities in physiological concentrations of ...

Cold Denaturation of the Hammerhead Ribozyme [PDF]

open access: yesJournal of the American Chemical Society, 2002
Cold denaturation is a thermodynamic phenomenon resulting from a difference in the heat capacities, DeltaCp, of the folded and unfolded states of a macromolecule. Whereas this phenomenon has been extensively studied in proteins, it has been thought not to occur in nucleic acids due to a negligible DeltaCp of folding.

Hairpin Ribozyme Genes Curtail Alcohol Drinking: from Rational Design to in vivo Effects in the Rat

open access: yesMolecular Therapy: Nucleic Acids, 2016
Ribozyme genes were designed to reduce voluntary alcohol drinking in a rat model of alcohol dependence. Acetaldehyde generated from alcohol in the liver is metabolized by the mitochondrial aldehyde dehydrogenase (ALDH2) such that diminishing ALDH2 ...

Trans-acting aptazyme for conditional gene knockdown in eukaryotic cells

open access: yesMolecular Therapy: Nucleic Acids, 2023
Trans-acting hammerhead ribozyme inherits the advantages of being the smallest and best-characterized RNA-cleaving ribozyme, offering high modularity and the ability to cleave any desired sequence without the aid of any protein, as long as the target ...

Rolling circle RNA synthesis catalyzed by RNA

open access: yeseLife, 2022
RNA-catalyzed RNA replication is widely considered a key step in the emergence of life’s first genetic system. However, RNA replication can be impeded by the extraordinary stability of duplex RNA products, which must be dissociated for re-initiation of ...

How RNA acts as a nuclease:some mechanistic comparisons in the nucleolytic ribozymes [PDF]

open access: yes, 2017
Recent structural and mechanistic studies have shed considerable light on the catalytic mechanisms of nucleolytic ribozymes. The discovery of several new ribozymes in this class has now allowed comparisons to be made, and the beginnings of mechanistic ...
