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

A triplex ribozyme expression system based on a single hairpin ribozyme. [PDF]
Triplex ribozyme (RZ) configurations allow for the individual activity of trans-acting RZs in multiple expression cassettes (multiplex), thereby increasing target cleavage relative to conventionally expressed RZs. Although hairpin RZs have been advantageously compared to hammerhead RZs, their longer size and structural features complicated triplex ...

Force for ancient and recent life: viral and stem-loop RNA consortia promote life. [PDF]
Lytic viruses were thought to kill the most numerous host (i.e., kill the winner). But persisting viruses/defectives can also protect against viruses, especially in a ubiquitous virosphere. In 1991, Yarmolinsky et al.

Capturing the essence of folding and functions of biomolecules using Coarse-Grained Models
The distances over which biological molecules and their complexes can function range from a few nanometres, in the case of folded structures, to millimetres, for example during chromosome organization. Describing phenomena that cover such diverse length,

Classification of the nucleolytic ribozymes based upon catalytic mechanism [PDF]
The nucleolytic ribozymes carry out site-specific RNA cleavage reactions by nucleophilic attack of the 2’-oxygen atom on the adjacent phosphorus with an acceleration of a million-fold or greater.

Rolling circle transcription of ribozymes from promoterless single-stranded DNA nanocircles in mammalian cells [Ribozimlerin, promotorsuz tek-iplikli DNA çemberlerinin rolling circle transkripsiyonu ile memeli hücrelerinde üretimi] [PDF]
Self-processing hairpin ribozymes have been synthesized from promoterless singlestranded DNA circles (73 nt) within mammalian cells. Following lipid-mediated transient transfection, DNA circles were efficiently internalized by mouse L cells (OST7–1 ...

Mechanical unfolding of RNA hairpins
Mechanical unfolding trajectories, generated by applying constant force in optical tweezer experiments, show that RNA hairpins and the P5abc subdomain of the group I intron unfold reversibly.
