Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches
Chemistry – A European Journal, EarlyView.We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...

Witnessing the structural evolution of an RNA enzyme
eLife, 2021 An RNA polymerase ribozyme that has been the subject of extensive directed evolution efforts has attained the ability to synthesize complex functional RNAs, including a full-length copy of its own evolutionary ancestor.

Fully Reversible Regulation of 8‐17 DNAzyme Activity Using Nucleoside‐Based Diarylethenes
Chemistry – A European Journal, EarlyView.The site‐specific incorporation of nucleosidic diarylethenes into the 8–17 deoxyribozyme (DNAzyme) identified position 2.1 as optimal. Compound dU‐PhtBu enabled efficient light‐dependent control of catalytic activity, while maintaining thermal stability and reversibility.

Nucleobase participation in ribozyme catalysis
, 2005 We constructed a modified form of the VS ribozyme containing an imidazole ring in place of adenine at position 756. The novel ribozyme is active in both cleavage and ligation reactions. The reaction is efficient, although relatively slow. The results are

Functional identification of catalytic metal ion binding sites within RNA. [PDF]
PLoS Biology, 2005 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.

Chemistry – A European Journal, EarlyView.An electrophilic 5‐isothiocyanatomethyl uridine building block enables modular post‐synthetic RNA labeling with primary amine‐containing probes. Positioning the functionality in the major groove minimizes structural perturbation and allows facile conjugation of sensitive tags such as TEMPO spin labels for paramagnetic relaxation enhancement studies ...

Flanking Sequence Cotranscriptionally Regulates Twister Ribozyme Activity
, 2023 Small nucleolytic ribozymes are RNAs that cleave their own phosphodiester backbone. While proteinaceous enzymes are regulated by a variety of known mechanisms, methods of regulation for ribozymes remain unclear.

Enhancing CRISPR‐Cas12a base editing in plants with LbCas12a variants and introns
Journal of Integrative Plant Biology, EarlyView.Intron optimization of LbCas12a‐RRV improves cytosine and adenine base editing efficiency in plants, supports multiplexed and double‐strand break‐free genome modification, and expands precise genome engineering tools for crop breeding and plant functional research. ABSTRACT Cytosine base editors (CBEs) and adenine base editors (ABEs) are powerful tools
