Inhibition of Bacterial RNase P RNA by Phenothiazine Derivatives
There is a need to identify novel scaffolds and targets to develop new antibiotics. Methylene blue is a phenothiazine derivative, and it has been shown to possess anti-malarial and anti-trypanosomal activities.

RNA ligase ribozymes with a small catalytic core
Catalytic RNAs, or ribozymes, catalyze diverse chemical reactions that could have sustained primordial life in the hypothetical RNA world. Many natural ribozymes and laboratory evolved ribozymes exhibit efficient catalysis mediated by elaborate catalytic

Transient tether between the SRP RNA and SRP receptor ensures efficient cargo delivery during cotranslational protein targeting [PDF]
Kinetic control of macromolecular interactions plays key roles in biological regulation. An example of such control occurs in cotranslational protein targeting by the signal recognition particle (SRP), during which the SRP RNA and the cargo both ...

Structural and biochemical basis for DNA and RNA catalysis by human Topoisomerase 3β
The authors revealed novel roles of catalytic residues and divalent metal ions for hsTOP3B, the human RNA topoisomerase, and demonstrated the structural elements that kinetically modulate the DNA and RNA topoisomerase activities of TOP3B.

The origins and physical roots of life’s dual – metabolic and genetic – nature [PDF]
This review paper aims at a better understanding of the origin and physical foundation of life’s dual – metabolic and genetic – nature. First, I give a concise ‘top-down’ survey of the origin of life, i.e., backwards in time from extant DNA/RNA/protein ...

ARGONAUTE PIWI domain and microRNA duplex structure regulate small RNA sorting in Arabidopsis. [PDF]
Small RNAs (sRNAs) are loaded into ARGONAUTE (AGO) proteins to induce gene silencing. In plants, the 5'-terminal nucleotide is important for sRNA sorting into different AGOs.

Understanding the role of chromatin remodeling in the regulation of circadian transcription in Drosophila. [PDF]
Circadian clocks enable organisms to anticipate daily changes in the environment and coordinate temporal rhythms in physiology and behavior with the 24-h day-night cycle. The robust cycling of circadian gene expression is critical for proper timekeeping,

Mutational analysis of Trypanosoma brucei RNA editing ligase reveals regions critical for interaction with KREPA2. [PDF]
The Trypanosoma brucei parasite causes the vector-borne disease African sleeping sickness. Mitochondrial mRNAs of T. brucei undergo posttranscriptional RNA editing to make mature, functional mRNAs.
