Catalytic RNA and RNA Splicing [PDF]
The capacity of Watson-Crick base-pair complementarity to direct informational transactions basic to gene expression has long been appreciated. Among RNA molecules, it mediates mRNA-tRNA codon-anticodon pairing and the 16S rRNA-mRNA Shine-Dalgarno interaction.

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

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.

Catalytic RNA world relics in Dicer RNAs [PDF]
RNA interference (RNAi) is a naturally occurring phenomenon of RNA-mediated gene silencing that is highly conserved among multicellular organisms. In the first step of the pathway, long double- stranded RNA molecules are chopped into shorter duplexes with 2 nucleotide overhangs at both 3 ' ends by an endonuclease dubbed Dicer, the structure of which ...

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.
