Mutational analysis of Trypanosoma brucei RNA editing ligase reveals regions critical for interaction with KREPA2. [PDF]
PLoS ONE, 2015 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.

Error thresholds for self- and cross-specific enzymatic replication [PDF]
, 2010 The information content of a non-enzymatic self-replicator is limited by Eigen's error threshold. Presumably, enzymatic replication can maintain higher complexity, but in a competitive environment such a replicator is faced with two problems related to ...

Ribozymes: the characteristics and properties of catalytic RNAs [PDF]
FEMS Microbiology Reviews, 1999 Ribozymes, or catalytic RNAs, were discovered a little more than 15 years ago. They are found in the organelles of plants and lower eukaryotes, in amphibians, in prokaryotes, in bacteriophages, and in viroids and satellite viruses that infect plants. An example is also known of a ribozyme in hepatitis delta virus, a serious human pathogen.

Understanding the role of chromatin remodeling in the regulation of circadian transcription in Drosophila. [PDF]
, 2015 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,

Comprehensive sequence-to-function mapping of cofactor-dependent RNA catalysis in the glmS ribozyme. [PDF]
, 2020 Massively parallel, quantitative measurements of biomolecular activity across sequence space can greatly expand our understanding of RNA sequence-function relationships. We report the development of an RNA-array assay to perform such measurements and its

Functional plasticity of antibacterial EndoU toxins. [PDF]
, 2018 Bacteria use several different secretion systems to deliver toxic EndoU ribonucleases into neighboring cells. Here, we present the first structure of a prokaryotic EndoU toxin in complex with its cognate immunity protein.
