Ribozymes are catalytic RNAs that are attractive platforms for the construction of nanoscale objects with biological functions. We designed a dimeric form of the Tetrahymena group I ribozyme as a unit structure in which two ribozymes were connected in a ...

Distribution of graph-distances in Boltzmann ensembles of RNA secondary structures [PDF]
Large RNA molecules often carry multiple functional domains whose spatial arrangement is an important determinant of their function. Pre-mRNA splicing, furthermore, relies on the spatial proximity of the splice junctions that can be separated by very ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

The structure of a nucleolytic ribozyme that employs a catalytic metal ion
The TS ribozyme (originally called twister-sister) is a nucleolytic catalytic RNA. We present a crystal structure of the ribozyme in a pre-reactive conformation. Two co-axial helical stacks are organized by a three-way junction and two tertiary contacts.

The Therapeutic Potential of Ribozymes [PDF]
AbstractRibozymes are catalytic RNA molecules that recognize their target RNA in a highly sequence-specific manner. They can therefore be used to inhibit deleterious gene expression (by cleavage of the target mRNA) or even repair mutant cellular RNAs. Targets such as the mRNAs of oncogenes (resulting from base mutations or chromosome translocations, eg,

Background Traditional CRISPR/Cas9 systems that rely on U6 or U3 snRNA promoters (RNA polymerase III-dependent promoters) can only achieve constitutive gene editing in plants, hampering the functional analysis of specifically expressed genes.

In vitro Evolution and Engineering for Improved Ribozyme Polymerase Production [PDF]
According to the "RNA World Hypothesis" the first self replicating molecule formed from the prebiotic chemicals is the ribozyme. A model compartmentalized self replicating system for ribozyme polymerases is designed and used to improve activity,

Functional identification of catalytic metal ion binding sites within RNA. [PDF]
The viability of living systems depends inextricably on enzymes that catalyze phosphoryl transfer reactions. For many enzymes in this class, including several ribozymes, divalent metal ions serve as obligate cofactors.

Hepatocellular carcinoma (HCC) has high fatality rate and limited therapeutic options. Here, we propose a new anti-HCC approach with high cancer-selectivity and efficient anticancer effects, based on adenovirus-mediated Tetrahymena group I trans-splicing
